The bridge crack produced the reason to simply analyseIn recent years, the traffic capital construction of our province gets swift and violent development, all parts have built a large number of concrete bridges. In the course of building and using in the bridge, relevant to influence project quality lead of common occurrence report that bridge collapse even because the crack appears The concrete can be said to " often have illness coming on " while fracturing and " frequently-occurring disease ", often perplex bridge engineers and technicians. In fact , if take certain design and construction measure, a lot of cracks can be overcome and controlled. For strengthen understanding of concrete bridge crack further, is it prevent project from endanger larger crack to try one's best, this text make an more overall analysis , summary to concrete kind and reason of production , bridge of crack as much as possible, in order to design , construct and find out the feasible method which control the crack , get the result of taking precautions against Yu WeiRan.Concrete bridge crack kind, origin cause of formation In fact, the origin cause of formation of the concrete structure crack is complicated and various, even many kinds of factors influence each other , but every crack has its one or several kinds of main reasons produced . The kind of the concrete bridge crack, on its reason to produce, can roughly divide several kinds as follows :(1) load the crack caused Concrete in routine quiet .Is it load to move and crack that produce claim to load the crack under the times of stress bridge, summing up has direct stress cracks , two kinds stress crack onces mainly. Direct stress crack refer to outside load direct crack that stress produce that cause. The reason why the crack produces is as follows, 1, Design the stage of calculating , does not calculate or leaks and calculates partly while calculating in structure; Calculate the model is unreasonable; The structure is supposed and accorded with by strength actually by strength ; Load and calculate or leak and calculate few; Internal force and matching the mistake in computation of muscle; Safety coefficient of structure is not enough. Do not consider the possibility that construct at the time of the structural design; It is insufficientto design the section; It is simply little and assigning the mistake for reinforcing bar to set up; Structure rigidity is insufficient; Construct and deal with improperly; The design drawing can not be explained clearly etc.. 2, Construction stage, does not pile up and construct the machines , material limiting ; Is it prefabricate structure structure receive strength characteristic , stand up , is it hang , transport , install to get up at will to understand; Construct not according to the design drawing, alter the construction order of the structure without authorization , change the structure and receive the strength mode; Do not do the tired intensity checking computations under machine vibration and wait to the structure . 3, Using stage, the heavy-duty vehicle which goes beyond the design load passes the bridge; Receive the contact , striking of the vehicle , shipping; Strong wind , heavy snow , earthquake happen , explode etc.. Stress crack once means the stress of secondary caused by loading outside produces the crack. The reason why the crack produces is as follows, 1, In design outside load function , because actual working state and routine , structure of thing calculate have discrepancy or is it consider to calculate, thus cause stress once to cause the structure to fracture in some position. Two is it join bridge arch foot is it is it assign " X " shape reinforcing bar , cut down this place way , section of size design and cut with scissors at the same time to adopt often to design to cut with scissors, theory calculate place this can store curved square in , but reality should is it can resist curved still to cut with scissors, so that present the crack and cause the reinforcing bar corrosion. 2, Bridge structure is it dig trough , turn on hole , set up ox leg ,etc. to need often, difficult to use a accurate one diagrammatic to is it is it calculate to imitate to go on in calculating in routine, set up and receive the strength reinforcing bar in general foundation experience. Studies have shown , after being dug the hole by the strength component , it will produce the diffraction phenomenon that strength flows, intensive near the hole in a utensil, produced the enormous stress to concentrate. In long to step prestressing force of the continuous roof beam , often block the steel bunch according to the needs of section internal force in stepping, set up the anchor head, but can often see the crack in the anchor firm section adjacent place. So if deal with improper, in corner or component form sudden change office , block place to be easy to appear crack strengthreinforcing bar of structure the. In the actual project, stress crack once produced the most common reason which loads the crack. Stress crack once belong to one more piece of nature of drawing , splitting off , shearing. Stress crack once is loaded and caused, only seldom calculate according to the routine too, but with modern to calculate constant perfection of means, times of stress crack to can accomplish reasonable checking computations too. For example to such stresses 2 times of producing as prestressing force , creeping ,etc., department's finite element procedure calculates levels pole correctly now, but more difficult 40 years ago. In the design, should pay attention to avoiding structure sudden change (or section sudden change), when it is unable to avoid , should do part deal with , corner for instance, make round horn , sudden change office make into the gradation zone transition, is it is it mix muscle to construct to strengthen at the same time, corner mix again oblique to reinforcing bar , as to large hole in a utensil can set up protecting in the perimeter at the terms of having angle steel. Load the crack characteristic in accordance with loading differently and presenting different characteristics differently. The crack appear person who draw more, the cutting area or the serious position of vibration. Must point out , is it get up cover or have along keep into short crack of direction to appear person who press, often the structure reaches the sign of bearing the weight of strength limit, it is an omen that the structure is destroyed, its reason is often that sectional size is partial and small. Receive the strength way differently according to the structure, the crack characteristic produced is as follows: 1, The centre is drawn. The crack runs through the component cross section , the interval is equal on the whole , and is perpendicular to receiving the strength direction. While adopting the whorl reinforcing bar , lie in the second-class crack near the reinforcing bar between the cracks. 2, The centre is pressed. It is parallel on the short and dense parallel crack which receive the strength direction to appear along the component. 3, Receive curved. Most near the large section from border is it appear and draw into direction vertical crack to begin person who draw curved square, and develop toward neutralization axle gradually. While adopting the whorl reinforcing bar , can see shorter second-class crack among the cracks. When the structure matches muscles less, there are few but wide cracks, fragility destruction may take place in thestructure 4, Pressed big and partial. Heavy to press and mix person who draw muscle a less one light to pigeonhole into the component while being partial while being partial, similar to receiving the curved component. 5, Pressed small and partial. Small to press and mix person who draw muscle a more one heavy to pigeonhole into the component while being partial while being partial, similar to the centre and pressed the component. 6, Cut. Press obliquly when the hoop muscle is too dense and destroy, the oblique crack which is greater than 45?? direction appears along the belly of roof beam end; Is it is it is it destroy to press to cut to happen when the hoop muscle is proper, underpart is it invite 45?? direction parallel oblique crack each other to appear along roof beam end. 7, Sprained. Component one side belly appear many direction oblique crack, 45?? of treaty, first, and to launch with spiral direction being adjoint. 8, Washed and cut. 4 side is it invite 45?? direction inclined plane draw and split to take place along column cap board, form the tangent plane of washing. 9, Some and is pressed. Some to appear person who press direction roughly parallel large short cracks with pressure.(2) crack caused in temperature changeThe concrete has nature of expanding with heat and contract with cold, look on as the external environment condition or the structure temperature changes, concrete take place out of shape, if out of shape to restrain from, produce the stress in the structure, produce the temperature crack promptly when exceeding concrete tensile strength in stress. In some being heavy to step foot-path among the bridge , temperature stress can is it go beyond living year stress even to reach. The temperature crack distinguishes the main characteristic of other cracks will be varied with temperature and expanded or closed up. The main factor is as follows, to cause temperature and change 1, Annual difference in temperature. Temperature is changing constantly in four seasons in one year, but change relatively slowly, the impact on structure of the bridge is mainly the vertical displacement which causes the bridge, can prop up seat move or set up flexible mound ,etc. not to construct measure coordinate , through bridge floor expansion joint generally, can cause temperature crack only when the displacement of the structure is limited, for example arched bridge , just bridge etc. The annual difference in temperature of our country generally changes therange with the conduct of the average temperature in the moon of January and July. Considering the creep characteristic of the concrete, the elastic mould amount of concrete should be considered rolling over and reducing when the internal force of the annual difference in temperature is calculated. 2, Rizhao. After being tanned by the sun by the sun to the side of bridge panel , the girder or the pier, temperature is obviously higher than other position, the temperature gradient is presented and distributed by the line shape . Because of restrain oneself function, cause part draw stress to be relatively heavy, the crack appears. Rizhao and following to is it cause structure common reason most , temperature of crack to lower the temperature suddenly 3, Lower the temperature suddenly. Fall heavy rain , cold air attack , sunset ,etc. can cause structure surface temperature suddenly dropped suddenly, but because inside temperature change relatively slow producing temperature gradient. Rizhao and lower the temperature internal force can adopt design specification or consult real bridge materials go on when calculating suddenly, concrete elastic mould amount does not consider converting into and reducing 4, Heat of hydration. Appear in the course of constructing, the large volume concrete (thickness exceeds 2. 0), after building because cement water send out heat, cause inside very much high temperature, the internal and external difference in temperature is too large, cause the surface to appear in the crack. Should according to actual conditions in constructing, is it choose heat of hydration low cement variety to try one's best, limit cement unit's consumption, reduce the aggregate and enter the temperature of the mould , reduce the internal and external difference in temperature, and lower the temperature slowly , can adopt the circulation cooling system to carry on the inside to dispel the heat in case of necessity, or adopt the thin layer and build it in succession in order to accelerate dispelling the heat. 5, The construction measure is improper at the time of steam maintenance or the winter construction , the concrete is sudden and cold and sudden and hot, internal and external temperature is uneven , apt to appear in the crack. 6, Prefabricate T roof beam horizontal baffle when the installation , prop up seat bury stencil plate with transfer flat stencil plate when welding in advance, if weld measure to be improper, iron pieces of nearby concrete easy to is it fracture to burn. Adopt electric heat piece draw law piece draw prestressing force at the component ,prestressing force steel temperature can rise to 350 degrees Centigrade , the concrete component is apt to fracture. Experimental study indicates , are caused the intensity of concrete that the high temperature burns to obviously reduce with rising of temperature by such reasons as the fire ,etc., glueing forming the decline thereupon of strength of reinforcing bar and concrete, tensile strength drop by 50% after concrete temperature reaches 300 degrees Centigrade, compression strength drops by 60%, glueing the strength of forming to drop by 80% of only round reinforcing bar and concrete; Because heat, concrete body dissociate ink evaporate and can produce and shrink sharply in a large amount(3) shrink the crack causedIn the actual project, it is the most common because concrete shrinks the crack caused. Shrink kind in concrete, plasticity shrink is it it shrinks (is it contract to do ) to be the main reason that the volume of concrete out of shape happens to shrink, shrink spontaneously in addition and the char shrink. Plasticity shrink. About 4 hours after it is built that in the course of constructing , concrete happens, the cement water response is fierce at this moment, the strand takes shape gradually, secrete water and moisture to evaporate sharply, the concrete desiccates and shrinks, it is at the same time conduct oneself with dignity not sinking because aggregate,so when harden concrete yet,it call plasticity shrink. The plasticity shrink producing amount grade is very big, can be up to about 1%. If stopped by the reinforcing bar while the aggregate sinks, form the crack along the reinforcing bar direction. If web , roof beam of T and roof beam of case and carry baseplate hand over office in component vertical to become sectional place, because sink too really to superficial obeying the web direction crack will happen evenly before hardenning. For reducing concrete plasticity shrink,it should control by water dust when being construct than,last long-time mixing, unloading should not too quick, is it is it take closely knit to smash to shake, vertical to become sectional place should divide layer build. Shrink and shrink (do and contract). After the concrete is formed hard , as the top layer moisture is evaporated progressively , the humidity is reduced progressively , the volume of concrete is reduced, is called and shrunk to shrink (do and contract). Because concrete top layermoisture loss soon, it is slow for inside to lose, produce surface shrink heavy , inside shrink a light one even to shrink, it is out of shape to restrain from by the inside concrete for surface to shrink, cause the surface concrete to bear pulling force, when the surface concrete bears pulling force to exceed its tensile strength, produce and shrink the crack. The concrete hardens after-contraction to just shrink and shrink mainly .Such as mix muscle rate heavy component (exceed 3% ), between reinforcing bar and more obvious restraints relatively that concrete shrink, the concrete surface is apt to appear in the full of cracks crackle. Shrink spontaneously. Spontaneous to it shrinks to be concrete in the course of hardenning , cement and water take place ink react, the shrink with have nothing to do by external humidity, and can positive (whether shrink, such as ordinary portland cement concrete), can negative too (whether expand, such as concrete, concrete of slag cement and cement of fly ash). The char shrinks. Between carbon dioxide and hyrate of cement of atmosphere take place out of shape shrink that chemical reaction cause. The char shrinks and could happen only about 50% of humidity, and accelerate with increase of the density of the carbon dioxide. The char shrinks and seldom calculates . The characteristic that the concrete shrinks the crack is that the majority belongs to the surface crack, the crack is relatively detailed in width , and criss-cross, become the full of cracks form , the form does not have any law . Studies have shown , influence concrete shrink main factor of crack as follows, 1, Variety of cement , grade and consumption. Slag cement , quick-hardening cement , low-heat cement concrete contractivity are relatively high, ordinary cement , volcanic ash cement , alumina cement concrete contractivity are relatively low. Cement grade low in addition, unit volume consumption heavy rubing detailed degree heavy, then the concrete shrinks the more greatly, and shrink time is the longer. For example, in order to improve the intensity of the concrete , often adopt and increase the cement consumption method by force while constructing, the result shrinks the stress to obviously strengthen . 2, Variety of aggregate. Such absorbing water rates as the quartz , limestone , cloud rock , granite , feldspar ,etc. are smaller, contractivity is relatively low in the aggregate; And such absorbing water rates as the sandstone , slate , angle amphibolite ,etc. are greater, contractivity is relatively high. Aggregate grains of foot-path heavy to shrink light inaddition, water content big to shrink the larger. 3, Water gray than. The heavier water consumption is, the higher water and dust are, the concrete shrinks the more greatly. 4, Mix the pharmaceutical outside. It is the better to mix pharmaceutical water-retaining property outside, then the concrete shrinks the smaller. 5, Maintain the method . Water that good maintenance can accelerate the concrete reacts, obtain the intensity of higher concrete. Keep humidity high , low maintaining time to be the longer temperature when maintaining, then the concrete shrinks the smaller. Steam maintain way than maintain way concrete is it take light to shrink naturall. 6, External environment. The humidity is little, the air drying , temperature are high, the wind speed is large in the atmosphere, then the concrete moisture is evaporated fast, the concrete shrinks the faster. 7, Shake and smash the way and time. Machinery shake way of smashing than make firm by ramming or tamping way concrete contractivity take little by hand. Shaking should determine according to mechanical performance to smash time , are generally suitable for 55s / time. It is too short, shake and can not smash closely knit , it is insufficient or not even in intensity to form the concrete; It is too long, cause and divide storey, thick aggregate sinks to the ground floor, the upper strata that the detailed aggregate stays, the intensity is not even , the upper strata incident shrink the crack. And shrink the crack caused to temperature, worthy of constructing the reinforcing bar againing can obviously improve the resisting the splitting of concrete , structure of especially thin wall (thick 200cm of wall ). Mix muscle should is it adopt light diameter reinforcing bar (8 |? construct 14 |? ) to have priority , little interval assign (whether @ 10 construct @ 15cm ) on constructing, the whole section is it mix muscle to be rate unsuitable to be lower than 0 to construct. 3%, can generally adopt 0 . 3%~0. 5%.(4), crack that causes out of shape of plinth of the groundBecause foundation vertical to even to subside or horizontal direction displacement, make the structure produce the additional stress, go beyond resisting the ability of drawing of concrete structure, cause the structure to fracture. The even main reason that subside of the foundation is as follows, 1, Reconnoitres the precision and is not enough for , test the materials inaccuratly in geology. Designing, constructing without fully grasping the geological situation, this is the main reason that cause the ground not to subside evenly .Such as hills area or bridge, district of mountain ridge,, hole interval to be too far when reconnoitring, and ground rise and fall big the rock, reconnoitring the report can't fully reflect the real geological situation . 2, The geological difference of the ground is too large. Building it in the bridge of the valley of the ditch of mountain area, geology of the stream place and place on the hillside change larger, even there are weak grounds in the stream, because the soil of the ground does not causes and does not subside evenly with the compressing. 3, The structure loads the difference too big. Under the unanimous terms, when every foundation too heavy to load difference in geological situation, may cause evenly to subside, for example high to fill out soil case shape in the middle part of the culvert than to is it take heavy to load both sides, to subside soon heavy than both sides middle part, case is it might fracture to contain 4, The difference of basic type of structure is great. Unite it in the bridge the samly , mix and use and does not expand the foundation and a foundation with the foundation, or adopt a foundation when a foot-path or a long difference is great at the same time , or adopt the foundation of expanding when basis elevation is widely different at the same time , may cause the ground not to subside evenly too 5, Foundation built by stages. In the newly-built bridge near the foundation of original bridge, if the half a bridge about expressway built by stages, the newly-built bridge loads or the foundation causes the soil of the ground to consolidate again while dealing with, may cause and subside the foundation of original bridge greatly 6, The ground is frozen bloatedly. The ground soil of higher moisture content on terms that lower than zero degree expands because of being icy; Once temperature goes up , the frozen soil is melted, the setting of ground. So the ground is icy or melts causes and does not subside evenly . 7, Bridge foundation put on body, cave with stalactites and stalagmites, activity fault,etc. of coming down at the bad geology, may cause and does not subside evenly . 8, After the bridge is built up , the condition change of original ground . After most natural grounds and artificial grounds are soaked with water, especially usually fill out such soil of special ground as the soil , loess , expanding in the land ,etc., soil body intensity meet water drop, compress out of shape to strengthen. In the soft soil ground , season causes the water table to drop to draw water or arid artificially, the ground soil layer consolidates and sinks again,reduce the buoyancy on the foundation at the same time , shouldering the obstruction of rubing to increase, the foundation is carried on one's shoulder or back and strengthened .Some bridge foundation is it put too shallow to bury, erode , is it dig to wash flood, the foundation might be moved. Ground load change of terms, bridge nearby is it is it abolish square , grit ,etc. in a large amount to put to pile with cave in , landslide ,etc. reason for instance, it is out of shape that the bridge location range soil layer may be compressed again. So, the condition of original ground change while using may cause and does not subside evenly Produce the structure thing of horizontal thrust to arched bridge ,etc., it is the main reason that horizontal displacement crack emerges to destroy the original geological condition when to that it is unreasonable to grasp incompletely , design and construct in the geological situation.桥梁裂缝产生原因浅析近年来,我省交通基础建设得到迅猛发展,各地建立了大量的混凝土桥梁。

中英文对照外文翻译(文档含英文原文和中文翻译)Create and comprehensive technology in the structure globaldesign of the buildingThe 21st century will be the era that many kinds of disciplines technology coexists , it will form the enormous motive force of promoting the development of building , the building is more and more important too in global design, the architect must seize the opportunity , give full play to the architect's leading role, preside over every building engineering design well. Building there is the global design concept not new of architectural design,characteristic of it for in an all-round way each element not correlated with building- there aren't external environment condition, building , technical equipment,etc. work in coordination with, and create the premium building with the comprehensive new technology to combine together.The premium building is created, must consider sustainable development , namely future requirement , in other words, how save natural resources as much as possible, how about protect the environment that the mankind depends on for existence, how construct through high-quality between architectural design and building, in order to reduce building equipment use quantity andreduce whole expenses of project.The comprehensive new technology is to give full play to the technological specialty of every discipline , create and use the new technology, and with outside space , dimension of the building , working in coordination with in an all-round way the building component, thus reduce equipment investment and operate the expenses.Each success , building of engineering construction condense collective intelligence and strength; It is intelligence and expectation that an architect pays that the building is created; The engineering design of the building is that architecture , structure , equipment speciality compose hardships and strength happenning; It is the diligent and sweat paid in design and operation , installation , management that the construction work is built up .The initial stage of the 1990s, our understanding that the concept of global design is a bit elementary , conscientious to with making some jobs in engineering design unconsciously , make some harvest. This text Hangzhou city industrial and commercial bank financial comprehensive building and Hangzhou city Bank of Communications financial building two building , group of " scientific and technological progress second prize " speak of from person who obtain emphatically, expound the fact global design - comprehensive technology that building create its , for reach global design outstanding architect in two engineering design, have served as the creator and persons who cooperate while every stage design and even building are built completely.Two projects come into operation for more than 4 years formally , run and coordinate , good wholly , reach the anticipated result, accepted and appreciated by the masses, obtain various kinds of honor .outstanding to design award , progress prize in science and technology , project quality bonus , local top ten view , best model image award ,etc., the ones that do not give to the architect and engineers without one are gratified and proud. The building is created Emphasizing the era for global design of the building, the architects' creation idea and design method should be broken through to some extent, creation inspirations is it set up in analysis , building of global design , synthesize more to burst out and at the foundation that appraise, learn and improve the integration capability exactly designed in building , possess the new knowledge system and thinking method , merge multi-disciplinary technology. We have used the new design idea in above-mentioned projects, have emphasized the globality created in building .Is it is it act as so as to explain to conceive to create two design overview and building of construction work these now.1) The financial comprehensive building of industrial and commercial bank of HangZhou,belong to the comprehensive building, with the whole construction area of 39,000 square meters, main building total height 84, 22, skirt 4 of room, some 6 storeys, 2 storeys of basements.Design overall thinking break through of our country bank building traditional design mode - seal , deep and serious , stern , form first-class function, create of multi-functional type , the style of opening , architecture integrated with the mode of the international commercial bank.The model of the building is free and easy, opened, physique was made up by the hyperboloid, the main building presented " the curved surface surrounded southwards ", skirt room presents " the curved surface surrounded northwards ", the two surround but become intension of " gathering the treasure ".Building flourishing upwards, elevation is it adopt large area solid granite wall to design, the belt aluminium alloy curtain wall of the large area and some glass curtain walls, and interweave the three into powerful and vigorous whole , chase through model and entity wall layer bring together , form concise , tall and straight , upward tendency of working up successively, have distinct and unique distinctions.Building level and indoor space are designed into a multi-functional type and style of opening, opening, negotiate , the official working , meeting , receiving , be healthy and blissful , visit combining together. Spacious and bright two storeys open in the hall unifiedly in the Italian marble pale yellow tone , in addition, the escalator , fountain , light set off, make the space seem very magnificent , graceful and sincere. Intelligent computer network center, getting open and intelligent to handle official business space and all related house distribute in all floor reasonably. Top floor round visit layer, lift all of Room visit layer , can have a panoramic view of the scenery of the West Lake , fully enjoy the warmth of the nature. 2) The financial building of Bank of Communications of Hangzhou, belong to the purely financial office block, with the whole construction area of 19,000 square meters, the total height of the building is 39.9 meters, 13 storeys on the ground, the 2nd Floor. Live in building degree high than it around location , designer have unique architectural appearance of style architectural design this specially, its elevation is designed into a new classical form , the building base adopts the rough granite, show rich capability , top is it burn granite and verticality bar and some form aluminum windows make up as the veneer to adopt, represent the building noble and refined , serious personality of the bank.While creating in above-mentioned two items, besides portraying the shape of the building and indoor space and outside environment minister and blending meticulously, in order to achieve the outstanding purpose of global design of the building , the architect , still according to the region and project characteristic, put forward the following requirement to every speciality:(1) Control the total height of the building strictly;(2) It favorable to the intelligent comfortable height of clearances to create; (3) Meet thefloor area of owner's demand;(4)Protect the environment , save the energy , reduce and make the investment;(5) Design meticulously, use and popularize the new technology; (6)Cooperate closely in every speciality, optimization design.Comprehensive technologyThe building should have strong vitality, there must be sustainable development space, there should be abundant intension and comprehensive new technology. Among above-mentioned construction work , have popularized and used the intelligent technology of the building , has not glued and formed the flat roof beam of prestressing force - dull and stereotyped structure technology and flat roof beam structure technology, baseplate temperature mix hole , technology of muscle and base of basement enclose new technology of protecting, computer control STL ice hold cold air conditioner technology, compounding type keeps warm and insulates against heat the technology of the wall , such new technologies as the sectional electricity distribution room ,etc., give architecture global design to add the new vitality of note undoubtedly.1, the intelligent technology of the buildingIn initial stage of the 1990s, the intelligent building was introduced from foreign countries to China only as a kind of concept , computer network standard is it soon , make information communication skeleton of intelligent building to pursue in the world- comprehensive wiring system becomes a kind of trend because of 10BASE-T. In order to make the bank building adapt to the development of the times, the designer does one's utmost to recommend and design the comprehensive wiring system with the leading eyes , this may well be termed the first modernized building which adopted this technical design at that time.(1) Comprehensive wiring system one communication transmission network, it make between speech and data communication apparatus , exchange equipment and other administrative systems link to each other, make the equipment and outside communication network link to each other too. It include external telecommunication connection piece and inside information speech all cable and relevant wiring position of data terminal of workspace of network. The comprehensive wiring system adopts the products of American AT&T Corp.. Connected up the subsystem among the subsystem , management subsystem , arterial subsystem and equipment to make up by workspace subsystem , level.(2) Automated systems of security personnel The monitoring systems of security personnel of the building divide into the public place and control and control two pieces of systemequipment with the national treasury special-purposly synthetically.The special-purpose monitoring systems of security personnel of national treasury are in the national treasury , manage the storehouse on behalf of another , transporting the paper money garage to control strictly, the track record that personnel come in and go out, have and shake the warning sensor to every wall of national treasury , the camera, infrared microwave detector in every relevant rooms, set up the automation of controlling to control.In order to realize building intellectuality, the architect has finished complete indoor environment design, has created the comfortable , high-efficient working environment , having opened up the room internal and external recreation space not of uniform size, namely the green one hits the front yard and roofing, have offered the world had a rest and regulated to people working before automation is equipped all day , hang a design adopt the special building to construct the node in concrete ground , wall at the same time.2, has not glued and formed the flat roof beam of prestressing force- dull and stereotyped structure technology and flat roof beam structure technologyIn order to meet the requirement with high assurance that the architect puts forward , try to reduce the height of structure component in structure speciality, did not glue and form the flat roof beam of prestressing force concrete - dull and stereotyped structure technology and flat roof beam structure technology after adopting.(1) Adopt prestressing force concrete roof beam board structure save than ordinary roof beam board concrete consumption 15%, steel consumption saves 27%, the roof beam reduces 300mm high.(2) Adopt flat roof beam structure save concrete about 10% consumption than ordinary roof beam board, steel consumption saves 6.6%, the roof beam reduces 200mm high.Under building total situation that height does not change , adopt above-mentioned structure can make the whole building increase floor area of a layer , have good economic benefits and social benefit.3, the temperature of the baseplate matches muscle technologyIn basement design , is it is it is it after calculating , take the perimeter to keep the construction technology measure warm to split to resist to go on to baseplate, arrange temperature stress reinforcing bar the middle cancelling , dispose 2 row receives the strength reinforcing bar up and down only, this has not only save the fabrication cost of the project but also met the basement baseplate impervious and resisting the requirement that splits.4, the foundation of the basement encloses and protects the new technology of design and operationAdopt two technological measures in enclosing and protecting a design:(1) Cantilever is it is it hole strength is it adopt form strengthen and mix muscle technology to design to protect to enclose, save the steel and invite 60t, it invests about 280,000 to save.(2) Is it is it protect of of elevation and keep roof beam technology to enclose , is it protect long to reduce 1.5m to enclose all to reduce, keep roof beam mark level on natural ground 1.5m , is it is it protect of lateral pressure receive strength some height to enclose to change, saving 137.9 cubic meters of concrete, steel 16.08t, reduces and invests 304,000 yuan directly through calculating.5, ice hold cold air conditioner technologyIce hold cold air conditioner technology belong to new technology still in our country , it heavy advantage that the electricity moves the peak and operates the expenses sparingly most. In design, is it ice mode adopt some (weight ) hold mode of icing , is it ice refrigeration to be plane utilization ratio high to hold partly to hold, hold cold capacity little , refrigeration plane capacity 30%-45% little than routine air conditioner equipment, one economic effective operational mode.Hold the implementation of the technology of the cold air conditioner in order to cooperate with the ice , has used intelligent technology, having adopted the computer to control in holding and icing the air conditioner system, the main task has five following respects:(1) According to the demand for user's cold load , according to the characteristic of the structure of the electric rate , set up the ice and hold the best operation way of the cold system automatically, reduce the operation expenses of the whole system;(2) Fully utilize and hold the capacity of the cold device, should try one's best to use up all the cold quantity held basically on the same day;(3) Automatic operation state of detection system, ensure ice hold cold system capital equipment normal , safe operation;(4) Automatic record parameter that system operate, display system operate flow chart and type systematic operation parameter report form;(5) Predict future cooling load, confirm the future optimization operation scheme.Ice hold cold air conditioner system test run for some time, indicate control system to be steady , reliable , easy to operate, the system operates the energy-conserving result remarkably.6, the compounding type keeps in the wall warm and insulates against heat To the area of Hangzhou , want heating , climate characteristic of lowering the temperature in summer in winter, is it protect building this structural design person who compound is it insulate against heat the wall to keep warm to enclose specially, namely: Fit up , keep warm , insulate against heat the three not to equal to the body , realize building energy-conservation better.Person who compound is it insulate against heat wall to combine elevation model characteristic , design aluminium board elevation renovation material to keep warm, its structure is: Fill out and build hollow brick in the frame structure, do to hang the American Fluorine carbon coating inferior mere aluminium board outside the hollow brick wall.Aluminium board spoke hot to have high-efficient adiabatic performance to the sun, under the same hot function of solar radiation, because the nature , color of the surface material are different from coarse degree, whether can absorb heat have great difference very , between surface and solar radiation hot absorption system (α ) and material radiation system (Cλ ) is it say to come beyond the difference this. Adopt α and Cλ value little surface material have remarkable result , board α、Cλ value little aluminium have, its α =0.26, Cλ =0.4, light gray face brick α =0.56, Cλ =4.3.Aluminium board for is it hang with having layer under air by hollow brick to do, because aluminium board is it have better radiation transfer to hot terms to put in layer among the atmosphere and air, this structure is playing high-efficient adiabatic function on indoor heating too in winter, so, no matter or can well realize building energy-conservation in winter in summer.7, popularize the technology of sectional electricity distribution roomConsider one layer paves Taxi " gold " value , the total distribution of the building locates the east, set up voltage transformer and low-voltage distribution in the same room in first try in the design, make up sectional electricity distribution room , save transformer substation area greatly , adopt layer assign up and down, mixing the switchyard system entirely after building up and putting into operation, the function is clear , the overall arrangement compactness is rational , the systematic dispatcher is flexible .

Formation Mechanism and Distribution of Paleogene-Neogene Stratigraphic Reservoirs in Jiyang DepressionAbstractDuring Paleogene-Neogene period, multiple scale unconformities had been formed in Jiyang depression, which provided favorable conditions for stratigraphic reservoirs. In recent years, various Paleogene-Neogene stratigraphic reservoirs in Jiyang depression have been found, and proved reserves were rising significantly, which fully showed a great exploration potential for this kind of reservoirs. But the practice of exploration in recent years indicated that the unconformities carrier system and its ability of sealing, petroleum migration and its accumulation model, distribution of stratigraphic reservoirs are uncertain, which deeply restrict the exploration degree of stratigraphic reservoirs in Jiyang depression.Based on the analysis of a large number of exploration wells and seismic data for Typical reservoirs, the paper analyses unconformities construct and its effect to generation in the Paleogene—Neogene, and summarize the distribution pattern of stratigraphic reservoirs based on petroleum mechanism and accumulation model. Finally, a highly quantitative prediction modclof height of pools in stratigraphic reservoirs was established, the research results effectively guided the explorationPra- ctice of stratigraphic reservoir .There are four macro unconformity types of Paleogene—Neogene formation which including truncation-overlap, truncation·paral lel, parallel—overlap and paralel unconformity in Jiyang depression.Besides truncation-overlap unconformity lies in slopes of depression, and parallel unconformity developed inside of depression,another two types lie in local areas. Unconformity can be developed vertically three-layer structure which including unconformity roof rock, weathered clay layer and semi-weathered rock. It also Can be two—layer structure if without weathered clay layer.And part of semi—weather rock Can be form a hard shell accuse of its filling process during the laterstage.Geological characteristic of the structure layer of unconformity is different in lithology,mineralogy, element geochemistry and weather degree index. Based on optimal partition of sequential number and principal component analysis, logging quantification recognition method about unconformity structure layers were established, on which effective identification of unconformitystnlcture layers can bu achieved in the case of no rock core. The formation of various unconformity structure types isrelated to many factors such as, parent rock lithology, interval of deposition hiatus, palaeotopography,and preservation conditions, which aretogether to control spatial distributions of unconformity structure types .Macro styles and its vertical structure of unconformity can be effected as a blocking, reservoir, trap or carrier system.Blocking affection to fluid depends on weathered clay layer,hard shell of semi-weathered rock and mudstone. So petroleum migration and accumulation units is relatively independence above and belowunconformity if structure layers mentioned above existed. Reservoir affection is due to permeable rock, including roof sandstone .Semi-weathered sandstone, semi-weathered carbonate rock, semi—weathered igneous rock and semi-weathered metamorphic. Trap—controlling affection related to macro unconformity type and its juxtapose to permeability and impermeability rock above and below unconformity. It is easy to develop stratigraphy traps where the permeability and impermeability beds juxtapose in a truncation-overlap unconformity, where up permeability and down impermeability in parallel-overlap unconformity, and down permeability and up impermeability beds juxtapose in a truncation-parallel. Transporting affection is owing to lateral continuity of permeable rock of unconformity. In a terrestrial rift basin, petroleum migration in transverse or vertical short distance in local area, and is not conducive to petroleum long distance along unconformity, because interbedding pattern of mudstone and sandstone is dominated, and its physical property of mudstone improved poorly .Because of the long distance from resource to trap, migration and accumulation procese is very complicated.. Accumulation process of Paleogene-Neogene stratigraphic traps can be summarized as following:allochthonous source rock , compound transportation , later period charging, buoyancy and pressure conversion driving for accumulation, and blocking by non-permeable layer of unconformity, Trap types and its distribution are controlled by unconformity structure styles. Petroleum distribution and its scale are controlled by generating ability of Source rock. Petroleum accumulation area is decided by positive tectonic units. If carrier systemexisted , oil column of stratigraphic reservoirs is effected by four mainfactors which including generation expulsion quantity,migrating distance, dip angle and capillary resistance of carrier layer. Based on the analysis of single factor, the prediction model of height of oil columu through multi—factor regressions was established . Based on the model , the paper defruited favorable areas, which reserves in these areas exceed 1.5 x 1 08t .Research results of the paper combined closely with exploration practice, and according to previous research results,31 exploration wells had been drilled, which of them 17 wells were successfully from 2006 to 2009. There is accumulation proved reserves Was up to 2362x104t. and predict reserves was to 3684x104t .Keywords:Paleogene; Neogene; unconformity stratigraphie reservoirs; Fomation mechanism; distribution pattern; Jiyang depression1. Preface1.1 Foundationnd and signifacance of the topic1.1.1 Theme originThe theme is from the Sinopcc project:Forming and distribution of Tertiarystratigraphic reservoir of Jiyang depression .Theme number:P06012,deadline:2006-20081.1.2 Foundation and baekground of the themeThe tectonic events frequently occurred in Jiyang depression in paleogene-Neogene.It was favour of forming stratigraphic reservoir because of existence of several kinds of unconformity . Based on statistical data , beneficial area reservoired oil is about 9500km2, and the remaining resource is about 16x 108t in stratigraphic reservoirs of paleogene-Neogene stratas.Since 1980s,many overlap and unconformity reservoirs have been founded , explored reserves Was apparently increased with deep exploring. By the end of 2006 , explored resource had been up to 3.7×108t which showed a large exploring potential.But , in fact , the research on stratigraphic reservoir is lack or Uttle , especially,Accumulation pattern and forecasting model of oil have not been studied systematically. For example , the successful ratio of exploration well testing which is the lowest in allkinds reservoirs Was only 35.7%about stratigraphie reservoir in paleogene-Neogene in Jiyang depression from2001-2005. The main loss reason for the overlap andunconformity reservoirs exploration is migration and trap of oil that is separently53.5%and 23.9%.Hereby , oil migration problem and trap validity are importantaspects for overlap and unconformity reservoir exploring.In short,it has three aspects as followed:(1)Shallow comprehension about conduction of ability of unconformity Research on unconformity in present indicated that it is not a simple surface three-dimension body which is important for migration of oil and gas.There has some deep knows about the basins in west China and the marine basins in China. The systematic theory is lack about structure characteristic which deeply affect accumulating oil and gas.(2)The remain uncertain migration and accumulation process of oil and gas about stratigraphic reservoir remain uncertain .Stratigraphic reservoir lay in edge of basin . So it is difficult to exactly hold accumulation regular of oil and gas because far distance traps and hydrocarbon resources make a complicated migration process.(3)Forecasting model of stratigraphic reservoir that could be used to guide explore is lack It is necessity to finely evaluate and explore stratigraphic reservoir along with degree of exploration. Mayor controlling factors remain uncertain in construction offorecasting model of stratigraphic reservoirs.1.1.3 Aim, sense and application value of themeThe study resolves the problem of statigraphic reservoir formation and distribution of Paleogene-Neogene in Jiyang depression. By analysis of uniformity structure, their affect on statigraphic reservoir formation will be identify; The accumulation model will be established through study on static geologic characteristic of statigraphic reservoir ; Forecast mode of oil extent will be achieved through research on oil extent and to predict oil quality.Research results Can not only be used to effectively guide statigraphic reservoirExploring, to raise drilling Success ratio, provide technical support for increasing oilproduction of the Sinopec, and also provide reference to statigraphic reservoir exploring of Bohai Bay area . Research will enormously deepen statigraphic reservoir accumulation regular and further enrich and improve subtle reservoir exploring theory .1.2 Research present at home and abroad1.2.1 Present research and development at home and abroadUnconformity reservoir is one of important exploring object since Levorsen proposed the concept of stratigraphic trap and then published paper on‘‘Stratigraphic oil field ” in 1 936.It turns into stratigraphic reservoir and lithology reservoir based on scholars deepenly research the Levorsen stratigraphic eservoir .Stratigraphic trap is formed as a result of the updip reservoir directly contigence with unconformity above. According to trap place, accurrence and barrier, stratigraphic oil pools is divided into overlap pool, unconformity barbered pool and ancient buried-hill pool .Unconformity reservoir research covers three main sections. One is unconformityand its effect on oil accumulating. The second section is developing paaem of stratigraphic trap. The third is mechanism of migrating and accumulating of oil and gas. Present studies mainly focus on the three sections above .(1)Unconformity and its effect on oil accumulationUnconformity is geology base and key element to form the overlap and unconformity barriered traps and relevant reservoir . In generally,research on overlap and unconformity barrier reservoirs is first unconformity research target.Oil geologists started to understand relationship between inconformity and oil and gas acumination in 1930s. Levorsen published the book of“geology of petroleumin'1954. The book entirely introduced definition and significance of unconformity and the relatiooships with oil accumulation .The research and application of unconformity were promoted by stratigraohy andrecent oil and gas accumulation theory,especially,thesequence stratigraohy pay a important role in predict of geological discontinuity .Pan zhongxiang[2’3]referred to unconformity importance for oil and gas accumulation in 1983. Unconformity is benefit to find petroleum because it is favour of oil and gas migration and accumulation. From 1990s, the research on unconformity and accumulation effect were also be done in Tarim basin, ordos basin, Bohai bay basin and Jungar basin, a important and innovation result were be achieved .Fuguang[4,5],Wu kongyou[l6,7]and Zhang jianlin[8]had noted that unconformity is not only a simple surface but also a special geology body, a migration and accumulation passageway of oil and gas. It is represent for tectonic movement, sea or lake suface change,and geologic alteration to earlier rocks.The inhomogeneity of alteration and later overlap make the a. rchitecture of unconformity. There ale three layers structure in a ideal unconformity: roof rock above unconformity, weathered clay horizon and semi-weathered rock.Unconformity formation is related to denudation time,climate, elevation, tectonic movement and lithology. Two layers structure layers were formed as the weathered clay horizon was lack. Liuhua[16], Suifenggui[17], etc. divided unconformity into four types sand/mud, sand/sand, mud/mud and mud/sand . According to lithologic deploy of unconformity. They refcred that the migrating and accumulating ability of unconformity are decided by lithologic deploy of unconformity .Panzhongxiang[2'3],Liuxiaohant[11],Zhangkeyin[12],Chenzhonghong[14],Hedengfa,Aihuaguo[19],Wuyajun[20],Chenjianping[22'23], Zhangjiguang[2l], John S[26]etc . had a deepresearch on unconformity and refered that unconformity has an apparent controllingeffect on oil and gas accumulation. In summery, five main aspects is included: charging reservoir, charging trap,charging migrating, charging accumulating anddestroying reservoir. Based on physical modeling of oil migration, Lv xiuzheng Bekele thought the oil migration is followed the rule “migration through thin bed”, namely, migration through prevailing passway, otherwise anywhere in a conformity .(2)Development regularity of stratigraphic trapsOverlapped and unconformity is premise of overlap and unconformity reservoirExiting. so, this kind reservoir developed based on overlapped and unconformity trap formation first.Chensizhong proposed four conditions for developing overlap and unconformity reservoirs in 1982 based on research on the characteristics of overlapped and unconformity reservoirs and its distribution patterns. First is that Multiple overlapped and unconformity reservoir formed as a result of Multiple unconformityies and overlaps.second is that oil avvumulation area is above and below unconformity nearby hydrocarbon source rock. Third is that Torque subsidence of dustpan depression cause wide rang of overlap and unconformity reservoir. Fourth is that favourable overlap and unconformity reservoir lies in anti-cycle litbofacies fold play. Tong xiao guang referred four main controlling factors in 1983. First is time, lithology, attitude and weathering degree of pre-Paleogene-Neogene base rocks. Second is structure of faulted depression and movement strength.Third is overlap distribution of overlap line and feature of overlap lay above unconformity. Fourth is distribution of unconformity surface, permeability of overburden rocks above unconformity. Hujianyi[1lreferred that unconformity is the base of forming overlap and unconformity barrier trap, but not all good trap exits bearby unconformity in 1 984 and 1 986. The basic condition of forming overlap and unconformity barrier trap are six elements:three lines and three surfaces. Three lines are lithologic wedging line, layer overlap line and intended zone contour line. Three surface are unconformity surface, adjacent rock surface of reservoir and fault surface. It exits kinds of trap types when six elementsarraies.People deeply know development regularity of overlap and unconformity trapwith sequence stratigraphy spring up. Zhangshanwen[31] refer that multi. type breakcontrol overlap and unconformity trap, base on researching sequence of Zhungaer basin, Bohaibay basin and Songliao basin in 2003. Lipilong[35-39] refer that tectonic and deposit control overlap and unconformity trap in 2003 and 2004. Tectonic movement cause basin up and down, formed large area exceed peel zone in edge of basin. It is benefit to form trap.Tectonic form nosing structures in basin. It is benefit to form traps, Deposit control reservoir and barrier layer forming. Yishiwei[42] propose that oil accumulation controlled three surface, lake extensive surface, unconformity surface and fault surface, according to Erlian basin, Jizhong depression overlap andinconformity reservoir characteristic. Overlap and unconformity reservoir distributionare controlled by truncation zone and overlap zone. Enriching is controlled by beneficial accumulating phase belt.(3)Oil and gas migration and accumulation mechanism of stratigraphic trapReservoir is resuk of oil and gas migrating and accumulating in long distance, due to stratigraphic trap far from hydracarbon source rock. It is controlled by migrating dynamic, passageway, path, distance and accumulation etc.Lipilong[35-39]refer that the most effective oil path is fault-sandfault-unconformity and fault-sand-unconformity compound transmit system for overlap and unconfortuity trap in 2003 and 2004.Lichunguang[44]refer that heavy crude is secondary gas/oil pool through unconformity path migrating and accumulating in unconformity accompany trap, based on researching feavy crude reservoir of Dongyingdepression in 1999. Zhangjiazhent and Wangyongshi[48]refer thatY'Lhezhuang reservoir mainly lie in 100m above old burial hill old layer reflect shaft in 2005. Capping formation and barrier formation control the accumulation of the area oil and gas. Better Capping formation and barrier formation, better oil accumulation Suifenggui[17]refers that it is key for stratigraphic trap accumulation that‘T-S’transmit system validity and ability consist of oil soures fault,sand and ubconformity in 2005 in Jiyang depression. Layer unconformity style affects the stratigraphy trap forming and oil and gas migration.Lvxiuxiang refer that migration in uncomformity is thin bed migration through oil migrating physical analog in 2000. Oil migrates along advantage path, but not unconformity surface.All in one, there are many researches and outcome about trap develop and oil/gas accumulation of land facies basin stratigraphy reservoir home and abroad. But trap forcast is difficult because stratigraphy lie in basin edge and changeable lithofacies.Accumulation regular known less than other type reservoir, especially how unconformity affect stratigraphic reservoir develop, accumulation process, model and distribution, because of long distance between trap and hydrocarbon ,complex migtation process.1.2.2 Developing tendencyOverlap and unconformity reservoir show more and more important position with development of un-anticlinal trap exploratory development and rising of degree of exploration of petroliferous basin.Survey showed that although large of reseach and probe,research of overlap and unconformity are limited at quality. But, the common understanding include following respects:(1)Evaluation of structure, carrier system and barrier abilityUnconformity is important to develop overlap and unconformitty barrier reservoir. Now research about unconformity focus on one angle. It is tendency that begins with contributing factor of unconformity, analysis structure, make definite forming characteristic, evaluate transmiting and barrier ability,analyze the relationship between unconformity and oil/gas reservoir. (2)Mayor controlling factors and developing regularity of overlap and unconformity reservoir.It is common understanding that key overlap and unconformity barrier trap formation in develop system in home and abroad. Based Oll many research, this type trap is controlled by reservoir, cap rock and crossrange barrier, especially their valid matching.However,there is not deep research on three elements on system and contributing because of exploration phase confinement.(3)Oil and gas migration mechanism and accumulation model of overlapped andstratigraphic reservoir.With long distance migration and accumulation, reservoir development relate toDynamic, fashion, path, distance, process, etc. Element. They limit the understandingabout oil migrating mechanism. It is tendency that based on quantification, combinating type dissect, establishing accumulating model, effectively guide unconformity reservoir exploration .1.3 Research content and technique route1.3.1 Research contentThe subject confh'm following three research contents in view of key problembased on research present and development tendency .(1)Characteristic and distribution ofunconformity architecturesBased on basin the evolution of basin structure and deposition, through structural geology and sedimentology, and combined lab analysis, geophysical interpretation and mathematical statistics, the geology characteristic of unconformity and mayor controlling factors were analysised to definite spatial distribution unconformity architectures .(2)Formation mechanism and accumulation model of stratigraphic reservoirBased on geology comprehensive research and mathematical statistics ofstatic-characteristic of stratigraphy reservoir and by analysis migration and accumulation.Process, the migration path, accumulation stage and accumulation dynamic mechanism were analyzed to evaluate unconformity affect on oil/gas accumulation in geological history .Based on above research, sum up stratigraphy reservoir accumulating mechanism of Paleogene-Neogene, establish accumulating model through positive and negative respects research .(3)Distribution paRem and predict of favorable area of stratigraphy reservoirAccording to accumulation process and model, sum up distribution of stratigraphy reservoir. Based on mathematics statistics and geology analysis, make definite main element and quantification token parameter of oilness altitude, probe quantification forcast model of oilness altitude of stratigraphy reservoir starting from oil/gas migrating and accumulation process .Based on research findings above, it mainly focus on forecasting of stratigraphicreservoir nearby unconformities between Paleogene—Neogene and pre—Paleogene, and between Neogene and Paleogene .1.3.2 Technique routeUsing for reference from outcome of predecessors, based on type characteristic and distribution of unconformity of Jiyang depression, keep layer unique feature and accumulation process dissecting loss trap analyze as key, make geology comprehensive research and mathematical statistics method, sum up accumulation process and model, sum up main element, establish quantification forcast model of trap oilness, evaluate benefit exploring area .Figl-1: Frame picture showing research technique route ofdistribution patternand formationof samigraphy reservoir in Paleogene and Neogene slratas in Jiyang depression济阳坳陷古近系一新近系地层油藏形成机制与分布规律摘要济阳坳陷古近系.新近系发育过程中,形成了多个规模不等的不整合,为地层油藏的发育提供了有利条件。

DESIGN AND EXECUTION OF GROUNDINVESTIGATION FOR EARTHWORKSPAUL QUIGLEY, FGSIrish Geotechnical Services LtdABSTRACTThe design and execution of ground investigation works for earthwork projects has becomeincreasingly important as the availability of suitable disposal areas becomes limited and costsof importing engineering fill increase. An outline of ground investigation methods which canaugment ,traditional investigation methods? particularly for glacial till / boulder clay soils is presented. The issue of ,geotechnical certification? is raised and recommendations outlined onits merits for incorporation with ground investigations and earthworks.1. INTRODUCTIONThe investigation and re-use evaluation of many Irish boulder clay soils presents difficultiesfor both the geotechnical engineer and the road design engineer. These glacial till or boulderclay soils are mainly of low plasticity and have particle sizes ranging from clay to boulders.Most of our boulder clay soils contain varying proportions of sand, gravel, cobbles and boulders in a clay or silt matrix. The amount of fines governs their behaviour and the silt content makes it very weather susceptible.Moisture contents can be highly variable ranging from as low as 7% for the hard grey blackDublin boulder clay up to 20-25% for Midland, South-West and North-West light grey boulderclay deposits. The ability of boulder clay soils to take-in free water is well established and poor planning of earthworks often amplifies this.The fine soil constituents are generally sensitive to small increases in moisture content whichoften lead to loss in strength and render the soils unsuitable for re-use as engineering fill. Many of our boulder clay soils (especially those with intermediate type silts and fine sand matrix) have been rejected at the selection stage, but good planning shows that they can infact fulfil specification requirements in terms of compaction and strength.The selection process should aim to maximise the use of locally available soils and with careful evaluation it is possible to use or incorporate ,poor or marginal soils? within fill area s and embankments. Fill material needs to be placed at a moisture content such that it is neither too wet to be stable and trafficable or too dry to be properly compacted.High moisture content / low strength boulder clay soils can be suitable for use as fill in lowheight embankments (i.e. 2 to 2.5m) but not suitable for trafficking by earthwork plant withoutusing a geotextile separator and granular fill capping layer. Hence, it is vital that the earthworks contractor fully understands the handling properties of the soils, as for many projects this is effectively governed by the trafficability of earthmoving equipment.2. TRADITIONAL GROUND INVESTIGATION METHODSFor road projects, a principal aim of the ground investigation is to classify the suitability of thesoils in accordance with Table 6.1 from Series 600 of the NRA Specification for Road Works(SRW), March 2000. The majority of current ground investigations for road works includes acombination of the following to give the required geotechnical data:Trial pitsCable percussion boreholesDynamic probingRotary core drillingIn-situ testing (SPT, variable head permeability tests, geophysical etc.)Laboratory testingThe importance of ,phasing? the fieldwork operations cannot be overstressed, particularly when assessing soil suitability from deep cut areas. Cable percussion boreholes are normallysunk to a desired depth or ,refusal? with disturbed and undisturbed samples recovered at 1.00m intervals or change of strata.In many instances, cable percussion boring is unable to penetrate through very stiff, hard boulder clay soils due to cobble, boulder obstructions. Sample disturbance in boreholes should be prevented and loss of fines is common, invariably this leads to inaccurate classification.Trial pits are considered more appropriate for recovering appropriate size samples and for observing the proportion of clasts to matrix and sizes of cobbles, boulders. Detailed and accurate field descriptions are therefore vital for cut areas and trial pits provide an opportunityto examine the soils on a larger scale than boreholes. Trial pits also provide an insight on trench stability and to observe water ingress and its effects.A suitably experienced geotechnical engineer or engineering geologist should supervise thetrial pitting works and recovery of samples. The characteristics of the soils during trial pit excavation should be closely observed as this provides information on soil sensitivity, especially if water from granular zones migrates into the fine matrix material. Very often, thecondition of soil on the sides of an excavation provides a more accurate assessment of its in-situ condition.3. SOIL CLASSIFICATIONSoil description and classification should be undertaken in accordance with BS 5930 (1999) and tested in accordance with BS 1377 (1990). The engineering description of a soil is basedon its particle size grading, supplemented by plasticity for fine soils. For many of our glacial till,boulder clay soils (i.e. ,mixed soils?) difficulties arise with descriptions and assessing engineering performance tests.As outlined previously, Irish boulder clays usually comprise highly variable proportions of sands, gravels and cobbles in a silt or clay matrix. Low plasticity soils with fines contents ofaround 10 to 15% often present the most difficulties. BS 5930 (1999) now recognises thesedifficulties in describing ,mixed soils? –the fine soil constituents which govern the engineering behaviour now takes priority over particle size.A key parameter (which is often underestimated) in classifying and understanding these soilsis permeability (K). Inspection of the particle size gradings will indicate magnitude of permeability. Where possible, triaxial cell tests should be carried out on either undisturbed samples (U100?s) or good quality core samples to evaluate the drainage characteristics of thesoils accurately.Low plasticity boulder clay soils of intermediate permeability (i.e. K of the order of 10-5 to 10-7 m/s) can often be ,conditioned? by drain age measures. This usually entails the installation of perimeter drains and sumps at cut areas or borrow pits so as to reduce the moisture content.Hence, with small reduction in moisture content, difficult glacial till soils can become suitableas engineering fill.4. ENGINEERING PERFORMANCE TESTING OF SOILSLaboratory testing is very much dictated by the proposed end-use for the soils. The engineering parameters set out in Table 6.1 pf the NRA SRW include a combination of thefollowing:Moisture contentParticle size gradingPlastic LimitCBRCompaction (relating to optimum MC)Remoulded undrained shear strengthA number of key factors should be borne in mind when scheduling laboratory testing:Compaction / CBR / MCV tests are carried out on < 20mm size material.Moisture content values should relate to < 20mm size material to provide a valid comparison.Pore pressures are not taken into account during compaction and may vary considerably between laboratory and field.Preparation methods for soil testing must be clearly stipulated and agreed with the designated laboratory.Great care must be taken when determining moisture content of boulder clay soils. Ideally, the moisture content should be related to the particle size and have a corresponding gradinganalysis for direct comparison, although this is not always practical.In the majority of cases, the MCV when used with compaction data is considered to offer thebest method of establishing (and checking) the suitability characteristics of a boulder clay soil.MCV testing during trial pitting is strongly recommended as it provides a rapid assessment ofthe soil suitability directly after excavation. MCV calibration can then be carried out in the laboratory at various moisture content increments. Sample disturbance can occur during transportation to the laboratory and this can have a significant impact on the resultant MCV?s.IGSL has found large discrepancies when performing MCV?s in the field on low plasticity boulder clays with those carried out later in the laboratory (2 to 7 days). Many of the aforementioned low plasticity boulder clay soils exhibit time dependant behaviour with significantly different MCV?s recorded at a later date –increased values can be due to the drainage of the material following sampling, transportation and storage while dilatancy and migration of water from granular lenses can lead to deterioration and lower values.This type of information is important to both the designer and earthworks contractor as it provides an opportunity to understand the properties of the soils when tested as outlined above. It can also illustrate the advantages of pre-draining in some instances. With mixed soils, face excavation may be necessary to accelerate drainage works.CBR testing of boulder clay soils also needs careful consideration, mainly with the preparationmethod employed. Design engineers need to be aware of this, as it can have an order of magnitude difference in results. Static compaction of boulder clay soils is advised as compaction with the 2.5 or 4.5kg rammer often leads to high excess pore pressures being generated – hence very low CBR values can result. Also, curing of compacted boulder claysamples is important as this allows excess pore water pressures to dissipate.5. ENGINEERING CLASSIFICATION OF SOILSIn accordance with the NRA SRW, general cohesive fill is categorised in Table 6.1 as follows: 2A Wet cohesive2B Dry cohesive2C Stony cohesive2D Silty cohesiveThe material properties required for acceptability are given and the design engineer then determines the upper and lower bound limits on the basis of the laboratory classification andengineering performance tests. Irish boulder clay soils are predominantly Class 2C.Clause 612 of the SRW sets out compaction methods. Two procedures are available:Method CompactionEnd-Product CompactionEnd product compaction is considered more practical, especially when good compaction control data becomes available during the early stages of an earthworks contract. A minimumTarget Dry Density (TDD) is considered very useful for the contractor to work with as a meansof checking compaction quality. Once the material has been approved and meets the acceptability limits, then in-situ density can be measured, preferably by nuclear gauge or sand replacement tests where the stone content is low.As placing and compaction of the fill progresses, the in-situ TDD can be checked and non-conforming areas quickly recognised and corrective action taken. This process requires the design engineer to review the field densities with the laboratory compaction plots and evaluate actualwith ,theoreticaldensities?.6. SUPPLEMENTARY GROUND INVESTIGATION METHODS FOR EARTHWORKSThe more traditional methods and procedures have been outlined in Section 2. The followingare examples of methods which are believed to enhance ground investigation works for roadprojects:Phasing the ground investigation works, particularly the laboratory testingExcavation & sampling in deep trial pitsLarge diameter high quality rotary core drilling using air-mist or polymer gel techniquesSmall-scale compaction trials on potentially suitable cut material6.1 PHASINGPhasing ground investigation works for many large projects has been advocated for many years –this is particularly true for road projects where significant amounts of geotechnical data becomes available over a short period. On the majority of large ground investigation projects no period is left to ,digest? or review the preliminary findings and re-appraise the suitability of the methods.With regard to soil laboratory testing, large testing schedules are often prepared with no real consideration given to their end use. In many cases, the schedule is prepared by a junior engineer while the senior design engineer who will probably design the earthworks will haveno real involvement.It is highlighted that the engineering performance tests are expensive and of long duration (e.g. 5 point compaction with CBR & MCV at each point takes in excess of two weeks). When classification tests (moisture contents, particle size analysis and Atterberg Limits) are completed then a more incisive evaluation can be carried out on the data and the engineering performance tests scheduled. If MCV?s are performed during trial pitting then a good assessment of the soil suitability can be immediately obtained.6.2 DEEP TRIAL PITSThe excavation of deep trial pits is often perceived as cumbersome and difficult and thereforenot considered appropriate by design engineers. Excavation of deep trial pits in boulder clay soils to depths of up to 12m is feasible using benching techniques and sump pumping of groundwater.In recent years, IGSL has undertaken such deep trial pits on several large road ground investigation projects. The data obtained from these has certainly enhanced the geotechnicaldata and provided a better understanding of the bulk properties of the soils.It is recommended that this work be carried out following completion of the cable percussionboreholes and rotary core drillholes. The groundwater regime within the cut area will play animportant role in governing the feasibility of excavating deep trial pits. The installation of standpipes and piezometers will greatly assist the understanding of the groundwater conditions, hence the purpose of undertaking this work late on in the ground investigation programme.Large representative samples can be obtained (using trench box) and in-situ shear strengthmeasured on block samples. The stability of the pit sidewalls and groundwater conditions canalso be established and compared with levels in nearby borehole standpipes or piezometers.Over a prominent cut area of say 500m, three deep trial pits can prove invaluable and the spoil material also used to carry out small-scale compaction trials.From a value engineering perspective, the cost of excavating and reinstating these excavations can be easily recovered. A provisional sum can be allocated in the ground investigation and used for this work.6.3 HIGH QUALITY LARGE DIAMETER ROTARY CORE DRILLINGThis system entails the use of large diameter rotary core drilling techniques using air mist orpolymer gel flush. Triple tube core drilling is carried out through the overburden soils with therecovered material held in a plastic core liner.Core recovery in low plasticity boulder clay has been shown to be extremely good (typically inexcess of 90%). The high core recovery permits detailed engineering geological logging andprovision of samples for laboratory testing.In drumlin areas, such as those around Cavan and Monaghan, IGSL has found the use of large diameter polymer gel rotary core drilling to be very successful in recovering very stiff /hard boulder clay soils for deep road cut areas (where cable percussion boreholes and trialpits have failed to penetrate). In-situ testing (vanes, SPT?s etc) can also be carried out withinthe drillhole to establish strength and bearing capacity of discrete horizons.Large diameter rotary drilling costs using the aforementioned systems are typically 50 to 60%greater than conventional HQ core size, but again from a value engineering aspect can provemuch more worthwhile due to the quality of geotechnical information obtained.6.4 SMALL-SCALE COMPACTION TRIALSThe undertaking of small-scale compaction trials during the ground investigation programmeis strongly advised,particularly where ,marginally suitable? soils are present in prominent cutareas. In addition to validating the laboratory test data, they enable more realistic planning ofthe earthworks and can provide considerable cost savings.The compaction trial can provide the following:Achievable field density, remoulded shear strength and CBREstablishing optimum layer thickness and number of roller passesResponse of soil during compaction (static v dynamic)Monitor trafficability & degree of rutting.A typical size test pad would be approximately 20 x 10m in plan area and up to 1.5m in thickness. The selected area should be close to the cut area or borrow pit and have adequateroom for stockpiling of material. Earthwork plant would normally entail a tracked excavator (CAT 320 or equivalent), 25t dumptruck, D6 dozer and either a towed or self-propelled roller.In-situ density measurement on the compacted fill by nuclear gauge method is recommendedas this facilitates rapid measurement of moisture contents, dry and bulk densities. It alsoenables a large suite of data to be generated from the compacted fill and to assess the relationship between degree of compaction, layer thickness and number of roller passes. Bothdisturbed and undisturbed (U100) samples of the compacted fill can be taken for laboratorytesting and validation checks made with the field data (particularly moisture contents). IGSL?sexperience is that with good planning a small-scale compaction trial takes two working daysto complete.7. SUPERVISION OF GROUND INVESTIGATION PROJECTSClose interaction and mutual respect between the ground investigation contractor and the consulting engineer is considered vital to the success of large road investigation projects. Asenior geotechnical engineer from each of the aforementioned parties should liase closely sothat the direction and scope of the investigation can be changed to reflect the stratigraphy andground conditions encountered.The nature of large ground investigation projects means that there must be good communication and flexibility in approach to obtaining data. Be prepared to compromise as methods and procedures specified may not be appropriate and site conditions can quickly change.From a supervision aspect (both contractor and consulting engineer), the emphasis should beon the quality of site-based geotechnical engineers, engineering geologists as opposed to quantity where work is duplicated.8. GEOTECHNICAL CERTIFICATIONThe Department of Transport (UK) prepared a document (HD 22/92) in 1992 for highway schemes. This sets out the procedures and documentation to be used during the planning and reporting of ground investigations and construction of earthworks.Road projects involving earthmoving activities or complex geotechnical features must be certified by the Design Organisation (DO) - consulting engineer or agent authority. The professional responsibility for the geotechnical work rests with the DO.For such a project, the DO must nominate a chartered engineer with appropriate geotechnicalengineering experience. He/she is referred to as the Geotechnical Liaison Engineer (GLE) and is responsible for all geotechnical matters including preparation of procedural statements,reports and certificates.Section 1.18 of HD 22/92 states that “on completion of the ground investigation works, the DO shall submit a report and certificate containing all the factual records and test results produced by the specialist contractor together with an interpretative report produced either bythe specialist contractor or DO”. The DO shall then prepare an Earthworks Design Report –this report is the Designer?s detailed report on his interpretation of the site investigation data and design of earthworks.The extent and closeness of the liaison between the Project Manager and the GLE will verymuch depend on the nature of the scheme and geotechnical complexities discovered as theinvestigation and design proceed.After the earthworks are completed, a geotechnical feedback report is required and is to beprepared by the DO. This addresses the geotechnical issues and problems encountered during the construction earthworks and corrective action or measures taken. Certificates are prepared by the DO to sign off on the geotechnical measures carried out (e.g. unstable slopes,karst features, disused / abandoned mine workings, ground improvement systems employed,etc).9. CONCLUSIONSClose co-operation is needed between ground investigation contractors and consulting engineers to ensure that the geotechnical investigation work for the roads NDP can be satisfactorily carried out.Many soils are too easily rejected at selection / design stage. It is hoped that the proposed methods outlined in this paper will assist design engineers during scoping andspecifying of ground investigation works for road projects.With modern instrumentation, monitoring of earthworks during construction is very straightforward. Pore water pressures, lateral and vertical movements can be easily measured and provide important feedback on the performance of the engineered soils.Phasing of the ground investigation works, particularly laboratory testing is considered vital so that the data can be properly evaluated.Disposal of ,marginal? soils will become increasingly difficult and more expensive as thewaste licensing regulations are tightened. The advent of landfill tax in the UK has seenthorough examination of all soils for use in earthworks. This is likely to provide a similarincentive and challenge to geotechnical and civil engineers in Ireland in the coming years.A certification approach comparable with that outlined should be considered by the NRAfor ground investigation and earthwork activities.土方工程的地基勘察与施工保罗·圭格利爱尔兰岩土工程服务有限公司摘要:当工程场地的处理面积有限且填方工程费用大量增加时,土方工程的地基勘察设计与施工已逐渐地变得重要。

外文资料The Ground-waterThe ources of water which supply water front below the earth's surface are called sub-surface sources or ground-water source.Groundwater storage is considerably in excess of all artificial and nature surface storage in the United States.Groundwater distribution may be generally categorize into zones of aeration and asterisked. The saturated zone ia one in which all the voids are filled with water under hydrostatic pressure.The aeration zone in whiche the interstices are filled partly with air and partly with waters, may be subdivided into three subsonic. The soil-water zone begins at the ground surface and extends downward through the major root zone of fire. Its total depth is variable and dependent on soil type and vegetation.The zone is unsaturated except during period of heavy infiltration.Threecategorise of water calssification may be encountered in this regional: hygroscopic water content, which is adsorbed from the air separation; capillary water rat, whiche is held by suifacetension;and gravitational waters, which is excess soil water draining through the soiled. The intermediate zone extends from the bottom of the soil-water zone to the top of the capillary fringe and may vary from nonexistence to several huntween the near-ground suiface region and the near-water-water table region through which infiltrating waters must passed. The capillary zone extends from the water table to a height determined by zone thickness ia a function of soil texture and may vary not ongly from region to region but also within a local area network.The water that can be drained from a soil by gravity is known as the specific yielding. It is expressed as the ratio of the volume of water that can be drained by gravity to the gross volume of the soil.Values of specific yield are dependent on soil particle size average, shape and distribution of pore, and degree of completion of the soiled. Average values of specific yield for alluvial aquifers range frome 10% to 20%.An aquifer is a water-bearing stratum or formation capble of transmitting water in quantities sufficient to permit development.Aquifers may be considered as falling into two categorise,confined and unconfined,depending on whether or not a water table or free within an aquifer is change whenever water is recharged to or discharged from an aquifer.Forsaturated,confinedaquifer,pressure changes produce only slight changs in storage volume.In this cases, the weight of the overburden is supposed partly by hydrostatic pressure and pattly by the soild material in the aquifer.When the hydrostatic pressure in a confined aquifer is reduced by pumping or other means,the load on the aquifer increase, causing its compressional, with theresult that some water is forced from its. Decreasing the hydrostatic pressure also causes a small expansione, which in turn produces an additional release of water.For confined aquifer, the water yield is expressed in terms of a storage coefficient Scarcely. This strong coefficient may be defined as the volume of water that an aquifer takes in or relleases per unit surface area of aquifer per unit change in head normal to the surface.In addition to water-bearing strata exhibiting satisfactory rates of yield,there are also non-water-bearing and impermeable strata.Anaquiclude is an impermeable stratum that may contain large quantities of water but whose transmission rates are ot high enough to permit effective development.Anaquifuge is a formation that is impermeable and devoid of waters.Any circumstance that alters the pressure imposed on underground water will also cause a variation in the groundwater level.Seasonalfactorshare, change in stream and river stages,evapotranspiration,atmospheric pressure change, windsor, ides, external load,various forms of withdrawal and recharge,and earthquakes all may produce fluctuations in the level of the water table or the piezometricsurface,depending on whether the aquifer is free or confined.It is important that the engineer concerned with the development and utilization of groundwater supplies be aware of these factors.He should also be able to evaluate their important relative to the operation of a specific groundwater basin.The rate of movement of water through the ground is of an entirely different magnitude than that through natural or artificial channels or canddits.Typical value range from 5 fr/day to a few feet per year.The collection of groundwater is accomplished primarily through the construction of wells or infiltration galleries.Numerous factors are involved in the numerical estimation of the performance of these collection works.Some cases are amenable to solution through the utilization of relatively simpie mathematical expectation.Other cases can be solved only through graphical analysis or the use of various kinds of models.A well system may be considered to be composed of three elements:the well structure,thepump,and the discharge piping.The well itself contains an open section through which flow enders and a casing through which the flow is transported to the groungsurface.The open section is usually a perforated casing or a slotted metal screen that permit the flow to enter and at the same time pervents collapse of the hole.Occasionally gravel is placed at the bottom the well casing aroung the screen.When a well is pumped,water is removed from the aquifer immediately adjacent to the screen.Flow then becomes established at locations some distance fromthe well in order to replenish this withdrawal.Owing to the resistance to flow offered by the soil,ahead loss is encountered and the piezometric surface adjacent to the well is depressed.This is known as the cone of depression.The cone of depression spreads until a condition of equilibrium is reached and steady-state conditions are established.Groundwater quantity is influenced considerably by the quality of the source.Changes in source waters or degraded quality of source source supplies may seriously impair the quality of the groundwater supply.Municipal and industrial wastes entering an aquifer are major sources of organic and inorganic rge-scale organic pollution of groundwater is infrequent,however,sincesignficant quantities of organic wastes usually cannot be easily introduced underground.The problem is quite different with inordinance are removed only with great difficulty.Inaddition,the effects of such pollution may continue for indefinite periods since dilution is slow and artificial flushing or treatment is generally impractical or too expensive.As the water passes through the soiled, a significant increase in the amounts of dissolved salt may occur.Theses salts are added by soluble products of soil weathering and of erosion by rainfall and flowing water.Locations downstream from heavily irrigation areas may find that the water they are receiving is too saline for satisfactory crop production.These saline contaminates are different to control because removal methods are receive methods are exceedingly expensive.A possible solution is to dilute with water of lower salt concentration(wastewater treatment plant effluent,for example)so that the average water produced by mixing will be suitable for use.Considerable care should be exercised to protect groundwater storage capacity from irreparable harm through the disposal of waste materials.The volumes of groundwater replaced annually through natural mechanisms are relatively small because of the slow rates of movement of groundwaters and the limited opportunity for surface waters to penetrate the earth's surface.To supplement this natural recharge process,a recent toward artificial recharge has been developing.In California,forexample,artificial recharge is presently a primary method of water conservation.Numerous methods are employed in artificial recharge operation.One of the most common plans is the utilization of holding basis.The usual practice is to impound the water in a series of reservoir arranged so that the overflow of one will enter the next,and so on.These artificial storage works are generally formed by the construction of dikes or levee.A second method is the modified streambed,which makes use of the natural water supply.The stream channel iswidened, leveled,scarified,or treated by a combination of methods to increase its recharge capability.Ditches and furrows are also used.The basic types of arrangement are the ground;the lateral type,in which water is diverted into a number of small furrows from the main canal or channel;and the tree-shaped or branching type,where water is deferred from the primary channel into successively smeller canalis and ditcher.Where slopes are relatively flat and uniform,floodiing provides an economical means of recharge.Normal practice is to spead the recharge water over the ground at relatively small depths so as not to disturb the soil or native vegetation.An additional method is the use of injection wells.Recharge rates are normally less than pimping rates for the same head condition,however,because of the clogging that is often encountered in the area adjacent to the well casing.Clogging may result from the entrapment of fine aquifer particle, from suspended material in the recharge water which is subsequently strained out and deposited in the vicinity of the well screen,from air binding,from chemical reactions between recharge and natural water,and from bacteria.For best result the recharge water should be clear,contain little or no sodium,and be chlorinated.地下水从地表下面提供水的水源叫做地下水。

土木工程专业毕业设计外文文献翻译2篇XXXXXXXXX学院学士学位毕业设计(论文)英语翻译课题名称英语翻译学号学生专业、年级所在院系指导教师选题时间Fundamental Assumptions for Reinforced ConcreteBehaviorThe chief task of the structural engineer is the design of structures. Design is the determination of the general shape and all specific dimensions of a particular structure so that it will perform the function for which it is created and will safely withstand the influences that will act on it throughout useful life. These influences are primarily the loads and other forces to which it will be subjected, as well as other detrimental agents, such as temperature fluctuations, foundation settlements, and corrosive influences, Structural mechanics is one of the main tools in this process of design. As here understood, it is the body of scientific knowledge that permits one to predict with a good degree of certainly how a structure of give shape and dimensions will behave when acted upon by known forces or other mechanical influences. The chief items of behavior that are of practical interest are (1) the strength of the structure, i. e. , that magnitude of loads of a give distribution which will cause the structure to fail, and (2) the deformations, such as deflections and extent of cracking, that the structure will undergo when loaded underservice condition.The fundamental propositions on which the mechanics of reinforced concrete is based are as follows:1.The internal forces, such as bending moments, shear forces, and normal andshear stresses, at any section of a member are in equilibrium with the effect of the external loads at that section. This proposition is not an assumption but a fact, because any body or any portion thereof can be at rest only if all forces acting on it are in equilibrium.2.The strain in an embedded reinforcing bar is the same as that of thesurrounding concrete. Expressed differently, it is assumed that perfect bonding exists between concrete and steel at the interface, so that no slip can occur between the two materials. Hence, as the one deforms, so must the other. With modern deformed bars, a high degree of mechanical interlocking is provided in addition to the natural surface adhesion, so this assumption is very close to correct.3.Cross sections that were plane prior to loading continue to be plan in themember under load. Accurate measurements have shown that when a reinforced concrete member is loaded close to failure, this assumption is not absolutely accurate. However, the deviations are usually minor.4.In view of the fact the tensile strength of concrete is only a small fraction ofits compressive strength; the concrete in that part of a member which is in tension is usually cracked. While these cracks, in well-designed members, are generally so sorrow as to behardly visible, they evidently render the cracked concrete incapable of resisting tension stress whatever. This assumption is evidently a simplification of the actual situation because, in fact, concrete prior to cracking, as well as the concrete located between cracks, does resist tension stresses of small magnitude. Later in discussions of the resistance of reinforced concrete beams to shear, it will become apparent that under certain conditions this particular assumption is dispensed with and advantage is taken of the modest tensile strength that concrete can develop.5.The theory is based on the actual stress-strain relation ships and strengthproperties of the two constituent materials or some reasonable equivalent simplifications thereof. The fact that novelistic behavior is reflected in modern theory, that concrete is assumed to be ineffective in tension, and that the joint action of the two materials is taken into consideration results in analytical methods which are considerably more complex and also more challenging, than those that are adequate for members made of a single, substantially elastic material.These five assumptions permit one to predict by calculation the performance of reinforced concrete members only for some simple situations. Actually, the joint action of two materials as dissimilar and complicated as concrete and steel is so complex that it has not yet lent itself to purely analytical treatment. For this reason, methods of design and analysis, while using these assumptions, are very largely based on the results of extensive and continuing experimental research. They are modified and improved as additional test evidence becomes available.钢筋混凝土的基本假设作为结构工程师的主要任务是结构设计。

INTRODUCTIONThe investigation and re-use evaluation of many Irish boulder clay soils presents difficulties for both the geotechnical engineer and the road design engineer. These glacial till or boulder clay soils are mainly of low plasticity and have particle sizes ranging from clay to boulders. Most of our boulder clay soils contain varying proportions of sand, gravel,cobbles and boulders in a clay or silt matrix. The amount of fines governs their behaviour and the silt content makes it very weather susceptible. Moisture contents can be highly variable ranging from as low as 7% for the hard grey black Dublin boulder clay up to 20-25% for Midland, South-West and North-West light grey boulder clay deposits. The ability of boulder clay soils to take-in free water is well established and poor planning of earthworks often amplifies this.The fine soil constituents are generally sensitive to small increases in moisture content which often lead to loss in strength and render the soils unsuitable for re-use as engineering fill. Many of our boulder clay soils (especially those with intermediate type silts and fine sand matrix) have been rejected at the selection stage, but good planning shows that they can in fact fulfil specification requirements in terms of compaction and strength.The selection process should aim to maximise the use of locally available soils and with careful evaluation it is possible to use or incorporate ‘poor or marginal soils’ within fill areas and embankments. Fill material needs to be placed at a moisture content such that it is neither too wet to be stable and trafficable or too dry to be properly compacted.High moisture content / low strength boulder clay soils can be suitable for use as fill in low height embankments (i.e. 2 to 2.5m) but not suitable for trafficking by earthwork plant without using a geotextile separator and granular fill capping layer. Hence, it is vital that the earthworks contractor fully understands the handling properties of the soils, as for many projects this is effectively governed by the trafficability of earthmoving equipment.2. TRADITIONAL GROUND INVESTIGATION METHODSFor road projects, a principal aim of the ground investigation is to classify the suitability of the soils in accordance with Table 6.1 from Series 600 of the NRA Specification for Road Works (SRW), March 2000. The majority of current ground investigations for road works includes a combination of the following to give the required geotechnical data:▪Trial pits▪Cable percussion boreholes▪Dynamic probing▪Rotary core drilling▪In-situ testing (SPT, variable head permeability tests, geophysical etc.)▪Laboratory testingThe importance of ‘phasing’ the fieldwork operations cannot be overstressed, particularly when assessing soil suitability from deep cut areas. Cable percussion boreholes are normally sunk to a desired depth or ‘refusal’ with disturbed and un disturbed samples recovered at 1.00m intervals or change of strata.In many instances, cable percussion boring is unable to penetrate through very stiff, hard boulder clay soils due to cobble, boulder obstructions. Sample disturbance in boreholes should be prevented and loss of fines is common, invariably this leads to inaccurate classification. Trial pits are considered more appropriate for recovering appropriate size samples and for observing the proportion of clasts to matrix and sizes of cobbles, boulders. Detailed and accurate field descriptions are therefore vital for cut areas and trial pits provide an opportunity toexamine the soils on a larger scale than boreholes. Trial pits also provide an insight on trench stability and to observe water ingress and its effects.A suitably experienced geotechnical engineer or engineering geologist should supervise the trial pitting works and recovery of samples. The characteristics of the soils during trial pit excavation should be closely observed as this provides information on soil sensitivity, especially if water from granular zones migrates into the fine matrix material. Very often, the condition of soil on the sides of an excavation provides a more accurate assessment of its in-situ condition.3. ENGINEERING PERFORMANCE TESTING OF SOILSLaboratory testing is very much dictated by the proposed end-use for the soils. The engineering parameters set out in Table 6.1 pf the NRA SRW include a combination of the following:▪Moisture content▪Particle size grading▪Plastic Limit▪CBR▪Compaction (relating to optimum MC)▪Remoulded undrained shear strengthA number of key factors should be borne in mind when scheduling laboratory testing:▪Compaction / CBR / MCV tests are carried out on < 20mm size material.▪Moisture content values should relate to < 20mm size material to provide a valid comparison.▪Pore pressures are not taken into account during compaction and may vary considerably between laboratory and field.▪Preparation methods for soil testing must be clearly stipulated and agreed with the designated laboratory.Great care must be taken when determining moisture content of boulder clay soils. Ideally, the moisture content should be related to the particle size and have a corresponding grading analysis for direct comparison, although this is not always practical.In the majority of cases, the MCV when used with compaction data is considered to offer the best method of establishing (and checking) the suitability characteristics of a boulder clay soil. MCV testing during trial pitting is strongly recommended as it provides a rapid assessment of the soil suitability directly after excavation. MCV calibration can then be carried out in the laboratory at various moisture content increments. Sample disturbance can occur during transportation to the laboratory and this can have a significant impact on the resultant MCV’s.IGSL has found large discrepancies when performing MCV’s in the field on low plasticity boulder clays with those carried out later in the laboratory (2 to 7 days). Many of the aforementioned low plasticity boulder clay soils exhibit time dependant behaviour with significantly different MCV’s recorded at a later date – increased values can be due to the drainage of the material following sampling, transportation and storage while dilatancy and migration of water from granular lenses can lead to deterioration and lower values.This type of information is important to both the designer and earthworks contractor as it provides an opportunity to understand the properties of the soils when tested as outlined above. It can also illustrate the advantages of pre-draining in some instances. With mixed soils, face excavation may be necessary to accelerate drainage works.CBR testing of boulder clay soils also needs careful consideration, mainly with the preparation method employed. Design engineers need to be aware of this, as it can have an order of magnitude difference in results. Static compaction of boulder clay soils is advised as compaction with the 2.5 or 4.5kg rammer often leads to high excess pore pressures being generated –hence very low CBR values can result. Also, curing of compacted boulder clay samples is important as this allows excess pore water pressures to dissipate.4. ENGINEERING CLASSIFICATION OF SOILSIn accordance with the NRA SRW, general cohesive fill is categorised in Table 6.1 as follows:▪2A Wet cohesive▪2B Dry cohesive▪2C Stony cohesive▪2D Silty cohesiveThe material properties required for acceptability are given and the design engineer then determines the upper and lower bound limits on the basis of the laboratory classification and engineering performance tests. Irish boulder clay soils are predominantly Class 2C.Clause 612 of the SRW sets out compaction methods. Two procedures are available:▪Method Compaction▪End-Product CompactionEnd product compaction is considered more practical, especially when good compaction control data becomes available during the early stages of an earthworks contract. A minimum Target Dry Density (TDD) is considered very useful for the contractor to work with as a means ofchecking compaction quality. Once the material has been approved and meets the acceptability limits, then in-situ density can be measured, preferably by nuclear gauge or sand replacement tests where the stone content is low.As placing and compaction of the fill progresses, the in-situ TDD can be checked and non-conforming areas quickly recognised and corrective action taken. This process requires the design engineer to review the field densities with the laboratory compaction plots and evaluate actual with ‘theoretical densities’.5. SUPPLEMENTARY GROUND INVESTIGATION METHODS FOR EARTHWORKSThe more traditional methods and procedures have been outlined in Section 2. The following are examples of methods which are believed to enhance ground investigation works for road projects:▪Phasing the ground investigation works, particularly the laboratory testing▪Excavation & sampling in deep trial pits▪Large diameter high quality rotary core drilling using air-mist or polymer gel techniques译文:土方工程的地基勘察与施工1、引言许多爱尔兰含砾粘土的勘察与再利用评价使岩土工程师与道路工程师感到为难。

专业英语翻译 subsoils and foundation

Loadings in buildings consist of the combined dead and imposed loads which exert a downward pressure upon the soil on which the structure is founded and this in turn promotes a reactive force in the form of an upward pressure from the soil. The structure is in effect sandwiched between these opposite pressures and the design of the building must be able to resist the resultant stresses set up within the structural members and the general building fabric. The supporting subsoil must be able to develop sufficient reactive force to give stability to the structure to prevent failure due to unequal settlement and to prevent failure of the subsoil due to shear. To enable a designer to select, design and detail a suitable foundation he (she) must have adequate data regarding the nature of the soil on which the structure will be founded and this is normally obtained from a planned soil investigation programmer.作用在建筑物上的恒荷载和外加荷载,会给建筑结构所处的地基土体施加一个向下的力,反过来,地基土也会产生一个向上的反作用力(作用到建筑结构上)建筑结构在反作用力的作用下必须是(完好的)有效的,建筑设计(必须考虑)能够抵抗来自建筑结构构件和普通房屋结构的合应力。

地基英文介绍

地基英文介绍Foundation, also known as footing, is an essential part of any construction project. It is the lowermost and supporting part of a structure, which transfers the weight of the building to the ground. The foundation provides stability, prevents settling, and protects the structure against moisture and other external factors.There are various types of foundations, including shallow and deep foundations. Shallow foundations are commonly used for smaller structures and are constructed close to the ground surface. They distribute the weight of the building evenly to the soil beneath. Some popular types of shallow foundations are strip foundations, raft foundations, and pad foundations.Deep foundations, on the other hand, are used when the soil near the surface cannot support the weight of the building. They need to reach deeper and rely on the stronger soil layers underneath. Pile foundations and caisson foundations are two examples of deep foundations. Pile foundations are made up of long, slender piles that are driven deep into the ground. Caisson foundations are large, hollow structures that are sunk into the ground and filled with concrete.The process of building a foundation involves several steps. First, the area is cleared of any vegetation or debris. Then, the soil is excavated to the required depth and compacted to ensure stability. Next, formwork is put in place to shape the foundation. Reinforcement bars are added, and concrete is poured into the formwork. The concrete is then cured and allowed to harden, forming a solid base for the structure.In addition to providing stability, the foundation also plays a crucial role in insulation and waterproofing. Special attention is given to ensuring that the foundation is properly insulated to prevent heat loss and maintain a comfortable indoor temperature. Waterproofing techniques are also applied to protect against water infiltration and moisture damage.Overall, the foundation is a critical component of any construction project. It provides a solid base for the structure, ensures stability, and protects against various environmental factors. A well-designed and properly constructed foundation is essential for the long-term durability and safety of any building.。

外文文献翻译Reinforced ConcreteConcrete and reinforced concrete are used as building materials in every country. In many, including the United States and Canada, reinforced concrete is a dominant structural material in engineered construction. The universal nature of reinforced concrete construction stems from the wide availability of reinforcing bars and the constituents of concrete, gravel, sand, and cement, the relatively simple skills required in concrete construction, and the economy of reinforced concrete compared to other forms of construction. Concrete and reinforced concrete are used in bridges, buildings of all sorts underground structures, water tanks, television towers, offshore oil exploration and production structures, dams, and even in ships.Reinforced concrete structures may be cast-in-place concrete, constructed in their final location, or they may be precast concrete produced in a factory and erected at the construction site. Concrete structures may be severe and functional in design, or the shape and layout and be whimsical and artistic. Few other building materials off the architect and engineer such versatility and scope.Concrete is strong in compression but weak in tension. As a result, cracks develop whenever loads, or restrained shrinkage of temperature changes, give rise to tensile stresses in excess of the tensile strength of the concrete. In a plain concrete beam, the moments about the neutral axis due to applied loads are resisted by an internal tension-compression couple involving tension in the concrete. Such a beam fails very suddenly and completely when the first crack forms. In a reinforced concrete beam, steel bars are embedded in the concrete in such a way that the tension forces needed for moment equilibrium after the concrete cracks can be developed in the bars.The construction of a reinforced concrete member involves building a from of mold in the shape of the member being built. The form must be strong enough to support both the weight and hydrostatic pressure of the wet concrete, and any forces applied to it by workers, concrete buggies, wind, and so on. The reinforcement is placed in this form and held in placeduring the concreting operation. After the concrete has hardened, the forms are removed. As the forms are removed, props of shores are installed to support the weight of the concrete until it has reached sufficient strength to support the loads by itself.The designer must proportion a concrete member for adequate strength to resist the loads and adequate stiffness to prevent excessive deflections. In beam must be proportioned so that it can be constructed. For example, the reinforcement must be detailed so that it can be assembled in the field, and since the concrete is placed in the form after the reinforcement is in place, the concrete must be able to flow around, between, and past the reinforcement to fill all parts of the form completely.The choice of whether a structure should be built of concrete, steel, masonry, or timber depends on the availability of materials and on a number of value decisions. The choice of structural system is made by the architect of engineer early in the design, based on the following considerations:1. Economy. Frequently, the foremost consideration is the overall const of the structure. This is, of course, a function of the costs of the materials and the labor necessary to erect them. Frequently, however, the overall cost is affected as much or more by the overall construction time since the contractor and owner must borrow or otherwise allocate money to carry out the construction and will not receive a return on this investment until the building is ready for occupancy. In a typical large apartment of commercial project, the cost of construction financing will be a significant fraction of the total cost. As a result, financial savings due to rapid construction may more than offset increased material costs. For this reason, any measures the designer can take to standardize the design and forming will generally pay off in reduced overall costs.In many cases the long-term economy of the structure may be more important than the first cost. As a result, maintenance and durability are important consideration.2. Suitability of material for architectural and structural function.A reinforced concrete system frequently allows the designer to combine the architectural and structural functions. Concrete has the advantage that it is placed in a plastic condition and is given the desired shapeand texture by means of the forms and the finishing techniques. This allows such elements ad flat plates or other types of slabs to serve as load-bearing elements while providing the finished floor and / or ceiling surfaces. Similarly, reinforced concrete walls can provide architecturally attractive surfaces in addition to having the ability to resist gravity, wind, or seismic loads. Finally, the choice of size of shape is governed by the designer and not by the availability of standard manufactured members.3. Fire resistance. The structure in a building must withstand the effects of a fire and remain standing while the building is evacuated and the fire is extinguished. A concrete building inherently has a 1- to 3-hour fire rating without special fireproofing or other details. Structural steel or timber buildings must be fireproofed to attain similar fire ratings.4. Low maintenance.Concrete members inherently require less maintenance than do structural steel or timber members. This is particularly true if dense, air-entrained concrete has been used for surfaces exposed to the atmosphere, and if care has been taken in the design to provide adequate drainage off and away from the structure. Special precautions must be taken for concrete exposed to salts such as deicing chemicals.5. Availability of materials. Sand, gravel, cement, and concrete mixing facilities are very widely available, and reinforcing steel can be transported to most job sites more easily than can structural steel. As a result, reinforced concrete is frequently used in remote areas.On the other hand, there are a number of factors that may cause one to select a material other than reinforced concrete. These include:1. Low tensile strength.The tensile strength concrete is much lower than its compressive strength ( about 1/10 ), and hence concrete is subject to cracking. In structural uses this is overcome by using reinforcement to carry tensile forces and limit crack widths to within acceptable values. Unless care is taken in design and construction, however, these cracks may be unsightly or may allow penetration of water. When this occurs, water or chemicals such as road deicing salts may cause deterioration or staining of the concrete. Special design details are required in such cases. In the case of water-retaining structures, special details and /of prestressing are required to prevent leakage.2. Forms and shoring. The construction of a cast-in-place structure involves three steps not encountered in the construction of steel or timber structures. These are ( a ) the construction of the forms, ( b ) the removal of these forms, and (c) propping or shoring the new concrete to support its weight until its strength is adequate. Each of these steps involves labor and / or materials, which are not necessary with other forms of construction.3. Relatively low strength per unit of weight for volume.The compressive strength of concrete is roughly 5 to 10% that of steel, while its unit density is roughly 30% that of steel. As a result, a concrete structure requires a larger volume and a greater weight of material than does a comparable steel structure. As a result, long-span structures are often built from steel.4. Time-dependent volume changes. Both concrete and steel undergo-approximately the same amount of thermal expansion and contraction. Because there is less mass of steel to be heated or cooled, and because steel is a better concrete, a steel structure is generally affected by temperature changes to a greater extent than is a concrete structure. On the other hand, concrete undergoes frying shrinkage, which, if restrained, may cause deflections or cracking. Furthermore, deflections will tend to increase with time, possibly doubling, due to creep of the concrete under sustained loads.In almost every branch of civil engineering and architecture extensive use is made of reinforced concrete for structures and foundations. Engineers and architects requires basic knowledge of reinforced concrete design throughout their professional careers. Much of this text is directly concerned with the behavior and proportioning of components that make up typical reinforced concrete structures-beams, columns, and slabs. Once the behavior of these individual elements is understood, the designer will have the background to analyze and design a wide range of complex structures, such as foundations, buildings, and bridges, composed of these elements.Since reinforced concrete is a no homogeneous material that creeps, shrinks, and cracks, its stresses cannot be accurately predicted by the traditional equations derived in a course in strength of materials forhomogeneous elastic materials. Much of reinforced concrete design in therefore empirical, i.e., design equations and design methods are based on experimental and time-proved results instead of being derived exclusively from theoretical formulations.A thorough understanding of the behavior of reinforced concrete will allow the designer to convert an otherwise brittle material into tough ductile structural elements and thereby take advantage of concrete’s desirable characteristics, its high compressive strength, its fire resistance, and its durability.Concrete, a stone like material, is made by mixing cement, water, fine aggregate ( often sand ), coarse aggregate, and frequently other additives ( that modify properties ) into a workable mixture. In its unhardened or plastic state, concrete can be placed in forms to produce a large variety of structural elements. Although the hardened concrete by itself, i.e., without any reinforcement, is strong in compression, it lacks tensile strength and therefore cracks easily. Because unreinforced concrete is brittle, it cannot undergo large deformations under load and fails suddenly-without warning. The addition fo steel reinforcement to the concrete reduces the negative effects of its two principal inherent weaknesses, its susceptibility to cracking and its brittleness. When the reinforcement is strongly bonded to the concrete, a strong, stiff, and ductile construction material is produced. This material, called reinforced concrete, is used extensively to construct foundations, structural frames, storage takes, shell roofs, highways, walls, dams, canals, and innumerable other structures and building products. Two other characteristics of concrete that are present even when concrete is reinforced are shrinkage and creep, but the negative effects of these properties can be mitigated by careful design.A code is a set technical specifications and standards that control important details of design and construction. The purpose of codes it produce structures so that the public will be protected from poor of inadequate and construction.Two types f coeds exist. One type, called a structural code, is originated and controlled by specialists who are concerned with the proper use of a specific material or who are involved with the safe design of a particular class of structures.The second type of code, called a building code, is established to cover construction in a given region, often a city or a state. The objective of a building code is also to protect the public by accounting for the influence of the local environmental conditions on construction. For example, local authorities may specify additional provisions to account for such regional conditions as earthquake, heavy snow, or tornados. National structural codes genrally are incorporated into local building codes.The American Concrete Institute ( ACI ) Building Code covering the design of reinforced concrete buildings. It contains provisions covering all aspects of reinforced concrete manufacture, design, and construction. It includes specifications on quality of materials, details on mixing and placing concrete, design assumptions for the analysis of continuous structures, and equations for proportioning members for design forces.All structures must be proportioned so they will not fail or deform excessively under any possible condition of service. Therefore it is important that an engineer use great care in anticipating all the probable loads to which a structure will be subjected during its lifetime.Although the design of most members is controlled typically by dead and live load acting simultaneously, consideration must also be given to the forces produced by wind, impact, shrinkage, temperature change, creep and support settlements, earthquake, and so forth.The load associated with the weight of the structure itself and its permanent components is called the dead load. The dead load of concrete members, which is substantial, should never be neglected in design computations. The exact magnitude of the dead load is not known accurately until members have been sized. Since some figure for the dead load must be used in computations to size the members, its magnitude must be estimated at first. After a structure has been analyzed, the members sized, and architectural details completed, the dead load can be computed more accurately. If the computed dead load is approximately equal to the initial estimate of its value ( or slightly less ), the design is complete, but if a significant difference exists between the computed and estimated values of dead weight, the computations should be revised using an improved value of dead load. An accurate estimate of dead load is particularly important when spans are long, say over 75 ft ( 22.9 m ),because dead load constitutes a major portion of the design load.Live loads associated with building use are specific items of equipment and occupants in a certain area of a building, building codes specify values of uniform live for which members are to be designed.After the structure has been sized for vertical load, it is checked for wind in combination with dead and live load as specified in the code. Wind loads do not usually control the size of members in building less than 16 to 18 stories, but for tall buildings wind loads become significant and cause large forces to develop in the structures. Under these conditions economy can be achieved only by selecting a structural system that is able to transfer horizontal loads into the ground efficiently.钢筋混凝土在每一个国家,混凝土及钢筋混凝土都被用来作为建筑材料。

7 Rigid-Frame StructuresA rigid-frame high-rise structure typically comprises parallel or orthogonally arranged bents consisting of columns and girders with moment resistant joints. Resistance to horizontal loading is provided by the bending resistance of the columns, girders, and joints. The continuity of the frame also contributes to resisting gravity loading, by reducing the moments in the girders.The advantages of a rigid frame are the simplicity and convenience of its rectangular form.Its unobstructed arrangement, clear of bracing members and structural walls, allows freedom internally for the layout and externally for the fenestration. Rigid frames are considered economical for buildings of up to' about25 stories, above which their drift resistance is costly to control. If, however,a rigid frame is combined with shear walls or cores, the resulting structure is very much stiffer so that its height potential may extend up to 50 stories or more. A flat plate structure is very similar to a rigid frame, but with slabs replacing the girders As with a rigid frame, horizontal and vertical loadings are resisted in a flat plate structure by the flexural continuity between the vertical and horizontal components.As highly redundant structures, rigid frames are designed initially on the basis of approximate analyses, after which more rigorous analyses and checks can be made. The procedure may typically include the following stages:1. Estimation of gravity load forces in girders and columns by approximate method.2. Preliminary estimate of member sizes based on gravity load forces witharbitrary increase in sizes to allow for horizontal loading.3. Approximate allocation of horizontal loading to bents and preliminary analysisof member forces in bents.4. Check on drift and adjustment of member sizes if necessary.5. Check on strength of members for worst combination of gravity and horizontalloading, and adjustment of member sizes if necessary.6. Computer analysis of total structure for more accurate check on memberstrengths and drift, with further adjustment of sizes where required. This stage may include the second-order P-Delta effects of gravity loading on the member forces and drift..7. Detailed design of members and connections.This chapter considers methods of analysis for the deflections and forces for both gravity and horizontal loading. The methods are included in roughly the order of the design procedure, with approximate methods initially and computer techniques later. Stability analyses of rigid frames are discussed in Chapter 16.7.1 RIGID FRAME BEHAVIORThe horizontal stiffness of a rigid frame is governed mainly by the bending resistance of the girders, the columns, and their connections, and, in a tall frame, by the axial rigidity of the columns. The accumulated horizontal shear above any story of a rigid frame is resisted by shear in the columns of that story (Fig. 7.1). The shear causes the story-height columns to bend in double curvature with points of contraflexure at approximately mid-story-height levels. The moments applied to a joint from the columns above and below are resisted by the attached girders, which also bend in double curvature, with points of contraflexure at approximately mid-span. These deformations of the columns and girders allow racking of the frame and horizontal deflection in each story. The overall deflected shape of a rigid frame structure due to racking has a shear configuration with concavity upwind, a maximum inclination near the base, and a minimum inclination at the top, as shown in Fig.7.1.The overall moment of the external horizontal load is resisted in each story level by the couple resulting from the axial tensile and compressive forces in the columns on opposite sides of the structure (Fig. 7.2). The extension and shortening of the columns cause overall bending and associated horizontal displacements of the structure. Because of the cumulative rotation up the height, the story drift due to overall bending increases with height, while that due to racking tends to decrease. Consequently the contribution to story drift from overall bending may, in. the uppermost stories, exceed that from racking. The contribution of overall bending to the total drift, however, will usually not exceed 10% of that of racking, except in very tall, slender,, rigid frames. Therefore the overall deflected shape of a high-rise rigid frame usually has a shear configuration.The response of a rigid frame to gravity loading differs from a simply connected frame in the continuous behavior of the girders. Negative moments are induced adjacent to the columns, and positive moments of usually lesser magnitude occur in the mid-span regions. The continuity also causes the maximum girder moments to be sensitive to the pattern of live loading. This must be considered when estimating the worst moment conditions. For example, the gravity load maximum hogging momentadjacent to an edge column occurs when live load acts only on the edge span and alternate other spans, as for A in Fig. 7.3a. The maximum hogging moments adjacent to an interior column are caused, however, when live load acts only on the spans adjacent to the column, as for B in Fig. 7.3b. The maximum mid-span sagging moment occurs when live load acts on the span under consideration, and alternate other spans, as for spans AB and CD in Fig. 7.3a.The dependence of a rigid frame on the moment capacity of the columns for resisting horizontal loading usually causes the columns of a rigid frame to be larger than those of the corresponding fully braced simply connected frame. On the other hand, while girders in braced frames are designed for their mid-span sagging moment, girders in rigid frames are designed for the end-of-span resultant hogging moments, which may be of lesser value. Consequently, girders in a rigid frame may be smaller than in the corresponding braced frame. Such reductions in size allow economy through the lower cost of the girders and possible reductions in story heights. These benefits may be offset, however, by the higher cost of the more complex rigid connections.7.2 APPROXIMATE DETERMINATION OF MEMBER FORCES CAUSED BY GRAVITY LOADSIMGA rigid frame is a highly redundant structure; consequently, an accurate analysis can be made only after the member sizes are assigned. Initially, therefore, member sizes are decided on the basis of approximate forces estimated either by conservative formulas or by simplified methods of analysis that are independent of member properties. Two approaches for estimating girder forces due to gravity loading are given here.7.2.1 Girder Forces—Code Recommended ValuesIn rigid frames with two or more spans in which the longer of any two adjacent spans does not exceed the shorter by more than 20 %, and where the uniformly distributed design live load does not exceed three times the dead load, the girder moment and shears may be estimated from Table 7.1. This summarizes the recommendations given in the Uniform Building Code [7.1]. In other cases a conventional moment distribution or two-cycle moment distribution analysis should be made for a line of girders at a floor level.7.2.2 Two-Cycle Moment Distribution [7.2].This is a concise form of moment distribution for estimating girder moments in a continuous multibay span. It is more accurate than the formulas in Table 7.1, especially for cases of unequal spans and unequal loading in different spans.The following is assumed for the analysis:1. A counterclockwise restraining moment on the end of a girder is positive anda clockwise moment is negative.2. The ends of the columns at the floors above and below the considered girder are fixed.3. In the absence of known member sizes, distribution factors at each joint aretaken equal to 1 /n, where n is the number of members framing into the joint in the plane of the frame.Two-Cycle Moment Distribution—Worked Example. The method is demonstrated by a worked example. In Fig, 7.4, a four-span girder AE from a rigid-frame bent is shown with its loading. The fixed-end moments in each span are calculated for dead loading and total loading using the formulas given in Fig, 7.5. The moments are summarized in Table 7.2.The purpose of the moment distribution is to estimate for each support the maximum girder moments that can occur as a result of dead loading and pattern live loading.A different load combination must be considered for the maximum moment at each support, and a distribution made for each combination.The five distributions are presented separately in Table 7.3, and in a combined form in Table 7.4. Distributions a in Table 7.3 are for the exterior supports A and E. For the maximum hogging moment at A, total loading is applied to span AB with dead loading only on BC. The fixed-end moments are written in rows 1 and 2. In this distribution only .the resulting moment at A is of interest. For the first cycle, joint B is balanced with a correcting moment of - (-867 + 315)/4 = - U/4 assigned to M BA where U is the unbalanced moment. This is not recorded, but half of it, ( - U/4)/2, is carried over to M AB. This is recorded in row 3 and then added to the fixed-end moment and the result recorded in row 4.The second cycle involves the release and balance of joint A. The unbalanced moment of 936 is balanced by adding -U/3 = -936/3 = -312 to M BA (row 5), implicitly adding the same moment to the two column ends at A. This completes the second cycle of the distribution. The resulting maximum moment at A is then given by the addition of rows 4 and 5, 936 - 312 = 624. The distribution for the maximum moment at E follows a similar procedure.Distribution b in Table 7.3 is for the maximum moment at B. The most severe loading pattern for this is with total loading on spans AB and BC and dead load only on CD. The operations are similar to those in Distribution a, except that the T first cycle involves balancing the two adjacent joints A and C while recording only their carryover moments to B. In the second cycle, B is balanced by adding - (-1012 + 782)/4 = 58 to each side of B. The addition of rows 4 and 5 then gives the maximum hogging moments at B. Distributions c and d, for the moments at joints C and D, follow patterns similar to Distribution b.The complete set of operations can be combined as in Table 7.4 by initially recording at each joint the fixed-end moments for both dead and total loading. Then the joint, or joints, adjacent to the one under consideration are balanced for the appropriate combination of loading, and carryover moments assigned .to the considered joint and recorded. The joint is then balanced to complete the distribution for that support.Maximum Mid-Span Moments. The most severe loading condition for a maximum mid-span sagging moment is when the considered span and alternate other spans and total loading. A concise method of obtaining these values may be included in the combined two-cycle distribution, as shown in Table 7.5. Adopting the convention that sagging moments at mid-span are positive, a mid-span total; loading moment is calculated for the fixed-end condition of each span and entered in the mid-span column of row 2. These mid-span moments must now be corrected to allow for rotation of the joints. This is achieved by multiplying the carryover moment, row 3, at the left-hand end of the span by (1 + 0.5 D.F. )/2, and the carryover moment at the right-hand end by -(1 + 0.5 D.F.)/2, where D.F. is the appropriate distribution factor, and recording the results in the middle column. For example, the carryover to the mid-span of AB from A = [(1 + 0.5/3)/2] x 69 = 40 and from B = -[(1+ 0.5/4)/2] x (-145) = 82. These correction moments are then added to the fixed-end mid-span moment to give the maximum mid-span sagging moment, that is, 733 + 40 + 82 = 855.7.2.3 Column ForcesThe gravity load axial force in a column is estimated from the accumulated tributary dead and live floor loading above that level, with reductions in live loading as permitted by the local Code of Practice. The gravity load maximum column moment is estimated by taking the maximum difference of the end moments in the connected girders and allocating it equally between the column ends just above and below the joint. To this should be added any unbalanced moment due to eccentricity of the girderconnections from the centroid of the column, also allocated equally between the column ends above and below the joint.第七章框架结构高层框架结构一般由平行或正交布置的梁柱结构组成,梁柱结构是由带有能承担弯矩作用节点的梁、柱组成。

Failed cases
There is only one "The Leaning Tower of Pisa " in the word,at most of time ,failed foundation always brings serious loss.
How to design?
• To make the foundation safe enough,when designing, what we should consider are as follows: →→:Pressure on the bottom of foundation less than its permissible value. →→:Settling amount of the building less than its permissible distortion value. →→:Ensuring the foundation has no danger of slip.

FOUNDATION ANALYSIS AND DESIGNFOUNDATIONSUBSOILSWe are concerned with placing the foundation on either soil or rock. This material may be under water as for certain bridge and marine structures, but more commonly we will place the foundation on soil or rock near the ground surface.Soil, being a mass of irregular-shaped particles of varying sizes, will consist of the particles (or solids), voids (pores or spaces) between particles, water in some of the voids, and air taking up the remaining void space. At temperatures below freezing the pore water may freeze, with resulting particle separation (volume increase).When the ice melts particles close up (volume decrease). If the ice is permanent, the ice-soil mixture is termed permafrost It is evident that the pore water is a variable state quantity that may be in the form of water vapor, water, or ice; the amount depends on climatic conditions, recency of rainfall, or soil location with respect to the GWT of Fig. 1-1.Soil is an aggregation of particles that may range very widely in size. It is the by-product of mechanical and chemical weathering of rock. Some of these particles are given specific names according to their sizes, such as gravel, sand, silt, clay, etc., and are more completely described in Sec. 2-7.Soil may be described as residual or transported. Residual soil is formed from weathering of parent rock at the present location. It usually contains angular rock fragments of varying sizes in the soil-rock interface zone. Transported soils are those formed from rock weathered at one location and transported by wind, water, ice, or gravity to the present site. The terms residual and transported must be taken in the proper context, for many current residual soils are formed (or are being formed) from transported soil deposits of earlier geological periods, which indurated into rocks. Later uplifts have exposed these rocks to a new onset of weathering. Exposed limestone, sandstone, and shale are typical of indurated transported soil deposits of earlier geological eras that have been uplifted to undergo current weathering and decomposition back to soil to repeat the geological cycle.Residual soils are usually preferred to support foundations as they tend to have better engineering properties. Soils that have been transported—particularly by wind or water—are often of poor quality. These are typified by small grain size, large amounts of pore space, potential for the presence of large amounts of pore water, and they often are highly compressible. Note, however, exceptions that produce poor-quality residual soils andgood-quality transported soil deposits commonly exist. In general, each site must be examined on its own merits.MAJOR FACTORS THAT AFFECTTHE ENGINEERING PROPERTIES OF SOILSMost factors that affect the engineering properties of soils involve geological processes acting over long time periods. Among the most important are the following.Natural Cementation and AgingAll soils undergo a natural cementation at the particle contact points. The process of aging seems to increase the cementing effect by a variable amount. This effect was recognized very early in cohesive soils but is now deemed of considerable importance in cohesionless deposits as well. The effect of cementation and aging in sand is not nearly so pronounced as for clay but still the effect as a statistical accumulation from a very large number of grain contacts can be of significance for designing a foundation. Care must be taken to ascertain the quantitative effects properly since sample disturbance and the small relative quantity of grains in a laboratory sample versus site amounts may provide difficulties in making a value measurement that is more than just an estimate. Field observations have well validated the concept of the cementation and aging process. Loess deposits, in particular, illustrate the beneficial effects of the cementation process where vertical banks are readily excavated.OverconsolidationA soil is said to be normally consolidated (nc) if the current overburden pressure(column of soil overlying the plane of consideration) is the largest to which the mass has ever been subjected. It has been found by experience that prior stresses on a soil element produce an imprint or stress history that is retained by the soil structure until a new stress state exceeds the maximum previous one. The soil is said to be overconsolidated (or preconsolidated) if the stress history involves a stress state larger than the present overburden pressure.Overconsolidated cohesive soils have received considerable attention. O nly more recentlyhas it been recognized that overconsolidation may be of some importance in cohesionless soils. A part of the problem, of course, is that it is relatively easy to ascertain overconsolidation in cohesive soils but very difficult in cohesionless deposits. The behavior of overconsolidated soils under new loads is different from that of normally consolidatedsoils, so it is important—particularly for cohesive soils—to be able to recognize the occurrence. The overconsolidation ratio (OCR) is defined as the ratio of the past effective pressure p'c to the present overburden pressure p' oOCR = P'c / P'oA normally consolidated soil has OCR = 1 and an overconsolidated soil has OCR > 1. OCR values of 1-3 are obtained for lightly overconsolidated soils. Heavily overconsolidated soils might have OCRs > 6 to 8.An underconsolidated soil will have OCR < 1. In this case the soil is still consolidating. Overor preconsolidation may be caused by a geologically deposited depth of overburden that has since partially eroded away.Of at leastequally common occurrence are preconsoli-dation effects that result from shrinkage stresses produced by alternating wet and dry cycles. These readily occur in arid and semiarid regions but can occur in more moderate climates as well. Chemical actions from naturally occurring compounds may aid in producing an over- consolidated soil deposit. Where overconsolidation occurs from shrinkage, it is common for only the top 1 to 3 meters to be overconsolidated and the underlying material to be normally consolidated. The OCR grades from a high value at or near the ground surface to 1 at the normally consolidated interface.Quality of the ClayThe term clay is commonly used to describe any cohesive soil deposit with sufficient clay minerals present that drying produces shrinkage with the formation of cracks or fissures such that block slippage can occur. Where drying has produced shrinkage cracks in the deposit we have a fissured clay. This material can be troublesome for field sampling because the material may be very hard, and fissures make sample recovery difficult. In laboratory strength tests the fissures can define failure planes and produce fictitiously low strength predictions (alternatively, testing intact pieces produces too high a prediction) compared to in situ tests where size effects may either bridge or confine the discontinuity. A great potential for strength reduction exists during construction where opening an excavation reduces the overburden pressure so that expansion takes place along any fissures. Subsequent rainwater or even local humidity can enter the fissure so that interior as well as surface softening occurs.A clay without fissures is an intact clay and is usually normally consolidated or at least has not been overconsolidated from shrinkage stresses. Although these clays mayexpand from excavation of overburden, the subsequent access to free water is not so potentially disastrous as for fissured clay because the water effect is more nearly confined to the surface.Mode of Deposit FormationSoil deposits that have been transported, particularly via water, tend to be made up of small grain sizes and initially to be somewhat loose with large void ratios. They tend to be fairly uniform in composition but may be stratified with alternating very fine material and thin sand seams, the sand being transported and deposited during high-water periods when stream velocity can support larger grain sizes. These deposits tend to stabilize and may become very compact (dense) over geological periods from subsequent overburden pressure as well as cementing and aging processes.Soil deposits developed'where the transporting agent is a glacier tend to be more varied in composition. These deposits may contain large sand or clay lenses. It is not unusual for glacial deposits to contain considerable amounts of gravel and even suspended boulders. Glacial deposits may have specific names as found in geology textbooks such as moraines, eskers, etc.; however, for foundation work our principal interest is in the uniformity and quality of the deposit. Dense, uniform deposits are usually not troublesome. Deposits with an erratic composition may be satisfactory for use, but soil properties may be very difficult to obtain. Boulders and lenses of widely varying characteristics may cause construction difficulties.The principal consideration for residual soil deposits is the amount of rainfall that has occurred. Large amounts of surface water tend to leach materials from the upper zones to greater d epths. A resulting stratum of fine particles at some depth can affect the strength and settlement characteristics of the siteSoil WaterSoil water may be a geological phenomenon; however, it can also be as recent as the latest rainfall or broken water pipe. An increase in water content tends to decrease the shear strength of cohesive soils. An increase in the pore pressure in any soil will reduce the shear strength. A sufficient increase can reduce the shear strength to zero—for cohesionless soils the end result is a viscous fluid. A saturated sand in a loose state can, from a sudden shock, also become a viscous fluid. This phenomenon is termed liquefaction and is ofconsiderable importance when considering major structures (such as power plants) in earthquake-prone areas.When soil water just dampens sand, the surface tension produced will allow shallow excavations with vertical sides. If the water evaporates, the sides will collapse; however, construction vibrations can initiate a cave-in prior to complete drying. The sides of a vertical excavation in a cohesive soil may collapse from a combination of rainfall softening the clay together with excess water enteringsurface tension cracks to create hydrostatic water pressure.In any case, the shear strength of a cohesive soil can be markedly influenced by water. Even without laboratory equipment, one has probably seen how cohesive soil strength can range from a fluid to a brick-like material as a mudhole alongside a road fills during a rain and subsequently dries. Ground cracks in the hole bottom after drying are shrinkage (or tension) cracks.Changes in the groundwater table (GWT) may produce undesirable effects—particularly from its lowering. Since water has a buoyant effect on soil as for other materials, lowering the GWT removes this effect and effectively increases the soil weight by that amount. This can produce settlements, for all the underlying soil "sees" is a stress increase from this weight increase. Very large settlements can be produced if the underlying soil has a large void ratio. Pumping water from wells in Mexico City has produced areal settlements of several meters. Pumping water (and oil) in the vicinity of Houston, Texas, has produced areal settlements of more than 2 meters in places. Pumping to dewater a construction site can produce settle ments of 30 to 50 mm within short periods of time. If adjacent buildings cannot tolerate this additional settlement, legal problems are certain to follow.地基分析与设计JOSEPH E.BOWLES地基土体人们一般关心基础是坐落在“土体”或是“岩体”之上。
