As the nature of the soil often varies considerably on the same construction site, the capacity of the soil to support loads also varies. Therefore, it is not always possible to provide a uniform size of foundation for the entire structure, even if it may support a uniform load. To improve the bearing capacity in varying ground conditions, soft spots are usually filled with consolidated hardcore or a weak concrete, before the foundation is laid. 翻译: 即便在同一施ቤተ መጻሕፍቲ ባይዱ场地,由于地基的性质有很大差异,土体 的承载力也不相同。所以,即使基础能承受相同的荷载, 要为整个结构设计出相同尺寸的基础并不总是可能的。为 了在不同的地基条件下提高基础的承载力,在浇注基础前, 通常用碎石垫层加固或用强度低的混凝土来填充土质松软 的地方。

civil-engineering-CHAPTER-TWO(土木工程概论英文课件)

civil-engineering-CHAPTER-TWO(土木工程概论英文课件)CHAPTER TWOPREPARATION FOR BEING A CIVIL ENGINEER The first step to be a civil engineer is generally to study civil engineering in a university or college, or major in主修civil engineering or other related programs. In most countries, the certificate (a document attesting to the truth of certain stated facts)of Registered Engineer注册工程师is only given to those who have accepted higher education in accredited (given official approval to act)programs. In this chapter, the reader will acquire the information about the typical(of a feature that helps to distinguish a person or thing)content of these programs.2 .1 What Kinds of Knowledge Are Necessary for a civil Engineer?Engineering education in universities domestic and abroad includes general education and special engineering education. At first, science and mathematics should be mentioned in general education. Engineering is a system of the applying of science and technology, so scientific principles set the foundation of engineering. This is the most important difference between modern civil engineering and ancient construction activities, although construction has always depended to some extent on scientific principles. Since the Industrial Revolution 工业革命, and even as far back as早在,远在the Renaissance(the revival of learning and culture), civil engineering has always been a branch of technologic science. For these reasons, science and mathematics become the common base of engineering educationincluding civil engineering education.Owing to the accumulation of several centuries, modern science has accumulated. a massive(containing a great quantity of matter)body of literature and knowledge.However, the beginner need not sit under apple tree to discover the laws of universal gravitation as Isaac Newton did in legend(a story about mythical). Neither does he have to exhaust (wear out completely)his brain for the principle of transform between energy and the mass. Based on the work of numerous pioneers, new students can now enter into the paradise of science easily. Nowadays, engineering is a synthetic system not only depending on traditional mechanics, but also closely relating to advanced science. You can find the courses such as Physics, Chemistry, Computer Science, Material Science, Environmental Science, and perhaps more, in your civil engineering program.One characteristic of modern science is that it can be described exactly and beautifully by mathematics. So the engineer should grasp this powerful tool to solve the problems they will meet in engineering analysis, design, planning and control. In this aspect, engineering students should learn advanced mathematics高等数学including analyticgeometry解析几何;分析几何学(the use of algebra代数学to study geometric properties);, differential and integral calculus 微积分, progression, differential equation微分方程(an equation containing differentials of a function). In addition, study of linear algebra线性代数, matrix, probability, numerical methods数值方法;计算方法is usually required by Civil Engineering Program. Using all of this knowledge, an engineer is able to predict preciselyimportant things about the project. For example, an engineercan tell whether a house or a bridge is safe or dangerous when earthquake occurs, or when it is hit by a hurricane. How can the skilled engineer do it? The engineer does this by using abstract models from physical objects(物理对象visible entity), which can be described and predicted by mathematics. Mathematics数学运算provides engineers with a solid foundation in their engineering activities. Furthermore, by strict training through verification确认,查证;核实(additional proof that something that was believed (some fact or hypothesis or theory) is correct), deduction推论(something that is inferred)and calculation in the study of mathematics, one will accustom oneself to logicality, strictness, and more rationality; important qualities for a good engineer.An engineer not only just takes the responsibility or the technology and production activities of a project but also has the duty to the society. Does your engineering project benefit your people and society or harm them? A qualified engineer should be conscientiously aware of this point at all times and for this reason universities also organize social science and humanities education for their students. Students enrolling in engineering programs should accept the education in this aspect. Philosophy, ethics, history, literature, aesthetics(the branch of philosophy dealing with beauty and taste (emphasizing the evaluative criteria that are applied to art), as well economics, management (the act of managing something)and foreign language are a useful and necessary tool.The necessary knowledge for professional occupation of civil engineering is composed of two parts; base knowledge for entire civil engineering and corresponding knowledge for a special aspect.Most civil engineering projects can be seen as varieties of structures. In order to ensure the safety of structures, civil engineers should understand their mechanical properties力学性能, such as forces, stresses (force that produces strain on a physical body), displacements (move something from its natural environment)and deformations(the act of twisting or deforming the shape of something)of the structures, caused by the weight of the structure itself and facilities, winds on the structure, vehicles车辆, varying of temperatures, and perhaps earthquakes. Courses, usually named mechanics of materials材料力学, structural analysis结构分析, elasticity(the tendency of a body to return to its original shape after it has been stretched or compressed), are set for this purpose. Because civil engineering projects are laid on or under the ground, to know soil and rock properties well is necessary. Thus geo-engineering, soil mechanics and foundation studies are also base knowledge. Water and wind, those will act on or react with the structures, have common properties in the view of mechanics, and fluid mechanics流体力学(study of the mechanics of fluids)deals with the concerned theories. Furthermore, a knowledge of engineering chart drawing (a skill to express the design idea by pictures in common rules understood by engineers* technicians and workers), surveying(to measure the landform for construction), and electricity, machinery, construction management建筑工程管理and general technic, budget(a sum of money allocated for a particular purpose), bidding投标;出价(the number of tricks a bridge player is willing to contract to make)the tendering are also required.绘制应力应变图Since civil engineering covers many fields of knowledge with many aspects which will be found in the rest chapters of thisbook, it is impossible to learn all of the knowledge in these areas. Almost all of the universities in the world to provide students with several options to enable them to specialize专门研究in the fields mentioned in Chapter One. Such a method is also being re-accepted by civil engineering education in China since 1998 although it was the way in the early history of higher civil engineering education before 1950s. For example, students can now choose options in building structures, bridge, tunnel, road pavement and construction, railway and so on, to know how to design, construct, and organize a civil engineering project. And the students are usually encouraged to choose more options for their future professional life.You can choose one of them as your direction2 2 What Can the University Education Provide for Students?COURSES: Basically, university offers students a variety of courses. The branches of knowledge mentioned above are involved in the courses and courses are usually divided into three types: requirement anything indispensable, approved electives批准选修, and free choice.The requirement and approval electives are both the courses that the students majored in must learn. There are some differences between the two types. Students can not miss any requirement course while have limited right to elect some of the approved electives. In that case那样的话a university usually tells students the minimum which they should choose in the list of the approval electives. As for关于the free choice, universities normally ask for a necessary number of credits or class hours. Those who hope to graduate and be awarded the corresponding degree, have to meet the requirement of the university or the school.Universities should continually adjust teaching plans and course tables 课程表with the development of science and technology, to meet the needs of future engineers. So the contents of courses are changed from time to time.TEACHERS: As in middle and high schools,teachers in universities give lectures, check homework, organize panel discussion专题讨论会(discussion of a subject of public interest by a group of persons forming a panel usually before an audience) for special problems, guide the students to experiments and also check answers in test sheets at the end of semester.Simultaneously, most of them play the role of scientists and/or engineers. They publish research papers研究论文in journals, spend much time in laboratory to verify a new discovery, test a renewal material with the engineering purpose, or design and make a new tool for engineering purpose. Some of them are registered engineers注册土木工程师if their field is civil engineering, and even have their own design institutes. In famous universities, when you knock a door to ask your professor a question, you will be probably told that the professor who you are talking is a respectable academician of Academy of Sciences orEngineering. The groups of wisdoms, who are good at theories and practice experience, are the best gift the universities afford to the students. Unlike the teachers in middle and high schools, university professors rarely monitor your daily study, because they appreciate students should study on individual initiative.With the development of internet, the tele-course is becoming fashionable. A young student will be in a puzzle about the large number of teachers in one university, but will find, faceto face lecture and discussion is always charming, and direct communication not limited in speech. Communication is also by means of expression of teacher's eyes and gestures. The close distance between you, your classmates and the lecturer, will make for an excited atmosphere, it is why since Socrates苏格拉底(古希腊哲学家)(ancient Athenian philosopher; teacher of Plato and Xenophon (470-399 BC), Confucius孔子(中国哲学家,教育家)(Chinese philosopher whose ideas and sayings were collected after his death and became the basis of a philosophical doctrine known a Confucianism (circa 551-478 BC), no matter how modern the society has become, and no matter what kind of high tech is introduced into the education process, the university always keeps its campus and excellent scholars学者们in a remarkable size.LABORATORY AND SITE PRACTICE BASE: For engineering colleges, the laboratories equipped with variety of test machines and measuring devices, and opened to students are indispensable. There are several types of experiments with special purpose, for demonstration, observation, validation确认;批准;生效(the act of validating; finding or testing the truth of something), practical training实习训练, exploration探究(a careful systematic search), or others. The basic experimental skill necessary for engineers can be learned in the laboratories. Most of test items测验项目are specified in the textbook, and detailed instruction is printed. In recent years, universities in China encourage students to design the experiments themselves, and do what they are interested in the related fields, to make students have the desire for innovation.It is cognized that a qualified engineer should possess rich experience obtained from engineering practice, so practicalexercise becomes one important part of the education plan of civil engineering program. Laboratory training is part of this practical training.Others are design work both in classroom and in workroom of consulting companies or design institutes, construction site work, geologic investigation地质勘察, surveying and measurement outside. In most cases Chinese universities, set practice bases at construction companies and design institutes. Usually students are requested to join the construction site work during the summer or winter vacation. A new procedure is tried in a few universities to ask students to search the projects being constructed and go there for their practical training. The procedure itself is taken as a practice. Most universities take the practical trainings to be requirement or approved electives.LIBRARY AND OTHER INFORMATION SOURCES: Self-study is a typical mode of university students. Successful students are always those who do not satisfy the contents of lectures and homework given by teachers. For themcomprehensive reading is undertaken outside indicated textbooks. Books, journals, reports and dissertations学位论文in the form of collection of printed pages打印页面which are stored in the book shelves are also read. Of course, the libraries in modern universities are reformed with the computer system and network, and the electronic libraries make it more convenient for students more convenience to borrow and read. The ability to search, find, and grasp information becomes more and more important in this age, and it is the task of the university education to let students have this ability.SPIRIT AND ATMOSPHERE: In the common sense, the universities are the place where there are freedom for thinking,equality in academy, and advocation of creation. Furthermore, the alternation of new students every year, make university campuses full of the energy of the younger generation.New student military trainingACTIVITIES OUT OF CLASS: there are different student organizations in the campus that help connect classroom to career, develop professionalism, increase technical proficiency, and refine ethical judgment. For example, the Institute of Civil Engineers (ICE) of British welcomes the students enrolled in program of civil engineering to be student members; even ICE develops its members in Chinese universities.Recently American Society of Civil Engineering ( ASCE) joined this action too. There are many sports teams for soccer, basketball, badminton, swimming, track and field, which are organized inter-class, department and even college. Societies in literatures and arts, will afford students a total different area from those in the class.2.3 What Abilities Shall a Future Civil Engineer Possess?THE ABILITY TO APPLY THE KNOWLEDGE:Elementary knowledge is essential to a civil engineering student. In common, by four-year period study, the student should be proficient熟练的,精通的in mathematics through differential equations 微分方程, probability and statistics概率论与数理统计, calculus-based physics微积分学, and general chemistry普通化学; proficiency ln the material mechanics材料力学, fluidmechanics流体力学, structural analysis and geo-techknowledge? good command of theprimary skills for engineering survey, drawing, test, and calculation and design, and at least deeper understanding several major civil engineering areas.The emphasis should be shifted to the application of the knowledge after we understand the importance of the knowledge. 'To know' is mere the first step. For engineers, the more important thing is to apply his knowledge i.e. natural science, mathematics and elementary engineering knowledge recorded in the textbooks or papers in the form of rules, principles, formulae and data, to solve engineering problems.THE ABILITY TO CONDUCT EXPERIMENTS AND EXPLAN THE RESULTS: The ability to plan and conduct experiments and analyse the results are basic aspects of the engineer's abilities.The future engineer is required to conduct laboratory experiments and to critically analyze and interpret data. Though many problems can be solved efficiently and economically by computation in a fine mechanical model, it is not everything. When new material or new structural system is used in civil engineering project, there are new variables which are not reflected, covered in the ready-made model. It will be dangerous if engineers do not change their mathematical model in time. However, how to calibrate the model? The most practical way is to do an experiment. Similar things also encounter in built-up or 'older' constructions, because there are many unknown factors. For example, material used in the structure will weaken, be damaged and lose its function through the duration of a structure's life while the change cannot usually be fully expected at the beginning. And on the other hand, the surroundings, conditions and real loads can also change. Engineers and researchers make the same phenomena, in most case, to recur (happen or occur again) in the laboratory, so that they can reveal the mechanism which now should be understood for the purpose of the safety of the structure. Though according to the basetheory, research engineers are able to judge the results of the experiments, it is common that the observed phenomena or obtained data in the experiments conflict with the known knowledge. In this case, the conflict will bring new discovery and improve an engineer's work. Give a rational explanation to a seemingly strange phenomenon is a wonderful task. It needs to synthesize knowledge of many subjects and to create new knowledge which is not mentioned or recorded in the literature.THE ABILITY OF DESIGN: For engineers, the ability to design a system, a component- or a procedure of construction is basically required. Civil engineers are creating substantial entities every day and everywhere in the world. Before they make them,they should be 'described'. It is the description of the non-existed entity that is called 'design'. The design shows what the future project is, and how to make it in a language which can be understood by constructors. The engineering design is quite different from the design of a piece of artwork, though we sometimes hear the admiration for a building as 'a graceful sculpture'. However, an artist can make a sculpture horse supporting only by one hoof, it will be impossible at ten times the size because the weight increases in three power of the size. Here the key factors will be functionality, safety and low-cost. It means that only the design which meets this requirements is practicable. So the engineering design work should obey the codes, specifications and guidance which arebased on scientific principles and the summary of accumulated experience. On the other hand, as an enterprising engineer. he or she never satisfies the existed ways or technics, so to search a possible way under the limited conditions to realize the 'impossible' things in design will be a challengeable butcharming work forever.THE ABILITY TO COOPERATE WITH WORKING TEAM: An engineer never work alone. Each project is a system, so the design work involves many people' efforts. For a big size building structure, the structural engineers should work with other experts from different disciplines, such as architects, surveyors, mechanical engineers and electricians. In the past, a skilful engineer would play several roles in a project with small size, but nowadays the different jobs should be taken by qualified engineers possessing certificates. When you are in the position of chief engineer in the work team, you should be in more harmony with your fellows. in order to cooperate with others well, every engineer should know how to hear and understand others, to consider things in both sides, you and your fellows, and to make necessary concession after discussion or even quarrels.THE ABILITY TO COMMUNICATE EFFECTIVELY:This is the ability which is an engineer should pay more attention to in the modern society. T o the engineer, as a designer, you should let your clients to accept your design, recognize that what you designed is the most suitable one in many possibilities; you should let the examiners and officers from government believe that your design accords with the low and specification so that the public and surroundings are safety? and you should let the contractors, manufacturers and construction companies understand your consideration and its rationality and feasibility. After being an engineer, you will find that you are frequently asked to attend meetings, to explain something for the project you designed, and you have to go to the construction site to hear new problems and tell the technician the answers. All of these need good communication unfortunately, until now our highschools and universities gave few chances to most of students to train their communication skills. Young engineering students now should take this seriously, and make great efforts to improve their communication ability.The basic element of communication is to speak. So try to look on your audience, no matter in seminars, in meetings or even in your friends' parties, make your voice loud, speak clearly and use plain but vivid vocabulary as possible.Besides speaking, the effective communication includes writing skill and expression of one's idea both in pictures and simple formulas. There are many skills you should learn, but the most important thing is to remember that the purpose of effective communication is for thoroughly understanding between you and your companion.Communication is not the same thing performing on a stage, where the key point should be exchange of information successfully. Good communication skill also includes hearing and considering companion's opinion. Discussion is also involved in the process of communication.2.4How Do You Match the Demands of the Program Education?Through four-year-period study to make yourselves acquire basic knowledge and training for being an engineer is one of the main targets that makes you enter into a university and enroll into a special engineering program.University is a new circumstance to freshmen students. For those who just left high school, and perhaps many of them are first time to sleep in dormitory of school, they should he familiar with the new life as early as possible.STUDY IN CLASSROOM: Needless to say, study is the mostimportant task. There are many things to 'study'. However, to study and understand the knowledge which are necessary for the education objectives as introduced previously in this chapter and specified by the program, education plan is the basic requirement.As a student, you have had the school experience more than ten years, so you know the study skill well; reading textbooks, attending the lectures, taking noteswhen listening, doing homework ............... .. those are almost the same as in high schools. But something changes.The engineering students usually do not have their fixed classroom. They should move from one building to another during the ten minute break between classes. Nobody shares one standard curriculum schedule with his classmates in the same program, especially in the junior and senior year. Students have the opportunity to choose what they 'prefer', and every one shall type the number of the course he wants to join in the next semester into the computer registered system, or after a long queue outside the administration office to fill in course register form. To Chinese students, the most difference from the traditional high school is perhaps that no teacher will strictly monitor your daily study life.Are you free? Certainly. But, just to certain extentSame as the other programs, the Civil Engineering Program requires necessary credits before you are approved to graduate from the university. Each course has its credits according to the class hours and the importance. After passing the examination, you can obtain the pointed credits. If the program asks its students to fulfill total 150 credits, you will never expect to be awarded the engineering bachelor degree in the case that youearned only 149 credits! Furthermore, as you have known, the courses you have to take are divided into three types, requirements, approval electives and free choice, but to each of the three types, the program education plan specifies a certain amount of credits you have to obtain. That is to say your freedom is not infinite.Sometimes, a student will be informed that he did not meet the requirement of the program because he does not pick enough credits in approval electives indicated by the program education plan. So, students had better to read program education plan and student manual carefully once enrolling in the program, and to follow it in the following days. What your tutor who is designated by the department for you, if any can do is to give you some suggestion or advice when you consider to choosesomething.To finish all the courses the program asks is important, and to get high points is encouraged. When you pursue advanced degree study, or apply for a good position1)i n your career life after graduation, high points are always helpful at the beginning. However, good students are not those who only know the description printed on the books or recite the formulae, but fail to explain practical phenomenon,to discover unknown things and to have strong motivation to create new knowledge himself. So university professors encourage students to consider problems in different views, and appreciate students to observe in their own eyes and to ask questions after thinking.JOIN ACTIVITIES IN CAMPUS OUT OF CLASS ACTIVELY: Since an engineer needs to learn effective communication with othersand smooth cooperation with work teams, and to be a good fellow and a success leader both in engineering and social activities, engineering students ought not to localize their 'study' only in academy or pure specialty. Fortunately, a university is such a school that provides with plenty of opportunities to those who would like to develop their multi-talents so that campus activities are called the 'amateurish classroom'. To join one or several activities which attract you in variety of campus activities, i.e. sports, drama and concerts, forums, competitions, clubs and reading party, will benefit your spirits and brain, enlarge your friend circle and get a way more comfortable to develop yourself. It is the university tradition to encourage students to join campus activities.PERSIST IN PHYSICAL EXERCISE: It is not a special requirement to civil engineering program students. Keeping in good health makes people to have confidence to live and work, to ensure the engineers energetically devote themselves into heavy work. By the way, though it is said not to work too heavy, in fact the work of civil engineers is really a heavy one, considering the duty engineer must take for the safety of human being and the society!Universities seek two main achievements in this aspect: to let the daily physical exercise become one of the personal customs of students and to train students to have some basic skills for physical exercise. Both of these are indispensable preparation for a qualified engineer.BE AWARE OF SOCIAL RESPOSSIBILITY:了解社会责任Why has society established a register engineer system, and why has this system been widely accepted by most of the industrial countries? The answer is that each engineering project that engineersinvolved in is not only a solution to a pure technical problem. At first, it will relate to the safety of life and estate. The failure of a building, collapse of a bridge or even a serious accident when undergoing construction may induce a real catastrophe to people, and make the loss of life and estate. So society asks that engineers who take the technical responsibility to the projects must be those who are qualified in knowledge and abilities. The procedure to cognize the candidate's qualification in engineering is the matter of register engineer system.With the development of natural and social science, people have more comprehensive understanding to human being and the relation with the world. In such a background, engineers should consider more and take larger responsibilities. The engineers are being required to understand the relation of his engineering projects with the society, and theinfluence of the projects on environment and continuous development. For example, if an industry building to be built will bring high benefits to investors, but also high risk to pollute the rivers and surrounding soils, what should the civil engineers do? The civil engineers shall be aware of the responsibility to cooperate with the experts in that field to solve the problem. In that case, a structural engineer may adjust the previous concept design if necessary.To be a responsible and conscientious engineer, the engineering student in the university should leave himself enough time to contact comprehensive knowledge about ethics, history and cultures of the different construction regions, beyond engineering subjects. The student needs to develop fine personality. A selfish person will be difficult to be a good engineer.。

Those who hope to graduate and be awarded the corresponding degree, have to meet the requirement of the university or the school.Universities should continually adjust teaching plans and course tables 课程表 with the development of science and technology, to meet the needs of future engineers. So the contents of courses are changed from time to time.TEACHERS: As in middle and high schools,teachers in universities give lectures, check homework, organize panel discussion专题讨论会(discussion of a subject of public interest by a group of persons forming a panel usually before an audience) for special problems, guide the students to experiments and also check answers in test sheets at the end of semester.Simultaneously, most of them play the role of scientists and/or engineers. They publish research papers研究论文in journals, spend much time in laboratory to verify a new discovery, test a renewal material with the engineering purpose, or design and make a new tool for engineering purpose. Some of them are registered engineers注册土木工程师if their field is civil engineering, and even have their own design institutes. In famous universities, when you knock a door to ask your professor a question, you will be probably told that the professor who you are talking is a respectable academician of Academy of Sciences orEngineering. The groups of wisdoms, who are good at theories and practice experience, are the best gift the universities afford to the students. Unlike the teachers in middle and high schools, university professors rarely monitor your daily study, because they appreciate students should study on individual initiative.With the development of internet, the tele-course is becoming fashionable. A young student will be in a puzzle about the large number of teachers in one university, but will find, face to face lecture and discussion is always charming, and direct communication not limited in speech. Communication is also by means of expression of teacher's eyes and gestures. The close distance between you, your classmates and the lecturer, will make for an excited atmosphere, it is why since Socrates苏格拉底(古希腊哲学家)(ancient Athenian philosopher; teacher of Plato and Xenophon (470-399 BC), Confucius孔子(中国哲学家,教育家)(Chinese philosopher whose ideas and sayings were collected after his death and became the basis of a philosophical doctrine known a Confucianism (circa 551-478 BC), no matter how modern the society has become, and no matter what kind of high tech is introduced into the education process, the university always keeps its campus and excellent scholars学者们in a remarkable size.•LABORATORY AND SITE PRACTICE BASE: For engineering colleges, the laboratories equipped with variety of test machines and measuring devices, and opened to students are indispensable. There are several types of experiments with special purpose, for demonstration, observation, validation确认;批准;生效(the act of validating; finding or testing the truth of something), practical training实习训练, exploration探究(a careful systematic search), or others. The basic experimental skill necessary for engineers can be learned in the laboratories. Most of test items测验项目are specified in the textbook, and detailed instruction is printed. In recent years, universities in China encourage students to design the experiments themselves, and do what they are interested in the related fields, to make students have the desire for innovation.It is cognized that a qualified engineer should possess rich experience obtained from engineering practice, so practical exercise becomes one important part of the education plan of civil engineering program. Laboratory training is part of this practical training.Others are design work both in classroom and in workroom of consulting companies or design institutes, construction site work, geologic investigation地质勘察, surveying and measurement outside. In most cases Chinese universities, set practice bases at construction companies and design institutes. Usually students are requested to join the construction site work during the summer or winter vacation. A new procedure is tried in a few universities to ask students to search the projects being constructed and go there for their practical training. The procedure itself is taken as a practice. Most universities take the practical trainings to be requirement or approved electives.•LIBRARY AND OTHER INFORMATION SOURCES: Self-study is a typical mode of university students. Successful students are always those who do not satisfy the contents of lectures and homework given by teachers. For themcomprehensive reading is undertaken outside indicated textbooks. Books, journals, reports and dissertations学位论文in the form of collection of printed pages打印页面which are stored in the book shelves are also read. Of course, the libraries in modern universities are reformed with the computer system and network, and the electronic libraries make it more convenient for students more convenience to borrow and read. The ability to search, find, and grasp information becomes more and more important in this age, and it is the task of the university education to let students have this ability.SPIRIT AND ATMOSPHERE: In the common sense, the universities are the place where there are freedom for thinking, equality in academy, and advocation of creation. Furthermore, the alternation of new students every year, make university campuses full of the energy of the younger generation.New student military trainingACTIVITIES OUT OF CLASS: there are different student organizations in the campus that help connect classroom to career, develop professionalism, increase technical proficiency, and refine ethical judgment. For example, the Institute of Civil Engineers (ICE) of British welcomes the students enrolled in program of civil engineering to be student members; even ICE develops its members in Chinese universities.Recently American Society of Civil Engineering ( ASCE) joined this action too. There are many sports teams for soccer, basketball, badminton, swimming, track and field, which are organized inter-class, department and even college. Societies in literatures and arts, will afford students a total different area from those in the class.2.3 What Abilities Shall a Future Civil Engineer Possess?•THE ABILITY TO APPLY THE KNOWLEDGE:Elementary knowledge is essential to a civil engineering student. In common, by four-year period study, the student should be proficient熟练的,精通的in mathematics through differential equations 微分方程, probability and statistics概率论与数理统计, calculus-based physics微积分学, and general chemistry普通化学; proficiency ln the material mechanics材料力学, fluidmechanics流体力学, structural analysis and geo-techknowledge? good command of theprimary skills for engineering survey, drawing, test, and calculation and design, and at least deeper understanding several major civil engineering areas.The emphasis should be shifted to the application of the knowledge after we understand the importance of the knowledge. 'To know' is mere the first step. For engineers, the more important thing is to apply his knowledge i.e. natural science, mathematics and elementary engineering knowledge recorded in the textbooks or papers in the form of rules, principles, formulae and data, to solve engineering problems.THE ABILITY TO CONDUCT EXPERIMENTS AND EXPLAN THE RESULTS: The ability to plan and conduct experiments and analyse the results are basic aspects of the engineer's abilities.The future engineer is required to conduct laboratory experiments and to critically analyze and interpret data. Though many problems can be solved efficiently and economically by computation in a fine mechanical model, it is not everything. When new material or new structural system is used in civil engineering project, there are new variables which are not reflected, covered in the ready-made model. It will be dangerous if engineers do not change their mathematical model in time. However, how to calibrate the model? The most practical way is to do an experiment. Similar things also encounter in built-up or 'older' constructions, because there are many unknown factors. For example, material used in the structure will weaken, be damaged and lose its function through the duration of a structure's life while the change cannot usually be fully expected at the beginning. And on the other hand, the surroundings, conditions and real loads can also change. Engineers and researchers make the same phenomena, in most case, to recur (happen or occur again) in the laboratory, so that they can reveal the mechanism which now should be understood for the purpose of the safety of the structure. Though according to the base theory, research engineers are able to judge the results of the experiments, it is common that the observed phenomena or obtained data in the experiments conflict with the known knowledge. In this case, the conflict will bring new discovery and improve an engineer's work. Give a rational explanation to a seemingly strange phenomenon is a wonderful task. It needs to synthesize knowledge of many subjects and to create new knowledge which is not mentioned or recorded in the literature.THE ABILITY OF DESIGN: For engineers, the ability to design a system, a component- or a procedure of construction is basically required. Civil engineers are creating substantial entities every day and everywhere in the world. Before they make them,they should be 'described'. It is the description of the non-existed entity that is called 'design'. The design shows what the future project is, and how to make it in a language which can be understood by constructors. The engineering design is quite different from the design of a piece of artwork, though we sometimes hear the admiration for a building as 'a graceful sculpture'. However, an artist can make a sculpture horse supporting only by one hoof, it will be impossible at ten times the size because the weight increases in three power of the size. Here the key factors will be functionality, safety and low-cost. It means that only the design which meets this requirements is practicable. So the engineering design work should obey the codes, specifications and guidance which arebased on scientific principles and the summary of accumulated experience. On the other hand, as an enterprising engineer. he or she never satisfies the existed ways or technics, so to search a possible way under the limited conditions to realize the 'impossible' things in design will be a challengeable but charming work forever.THE ABILITY TO COOPERATE WITH WORKING TEAM: An engineer never work alone. Each project is a system, so the design work involves many people' efforts. For a big size building structure, the structural engineers should work with other experts from different disciplines, such as architects, surveyors, mechanical engineers and electricians. In the past, a skilful engineer would play several roles in a project with small size, but nowadays the different jobs should be taken by qualified engineers possessing certificates. When you are in the position of chief engineer in the work team, you should be in more harmony with your fellows. in order to cooperate with others well, every engineer should know how to hear and understand others, to consider things in both sides, you and your fellows, and to make necessary concession after discussion or even quarrels.THE ABILITY TO COMMUNICATE EFFECTIVELY:This is the ability which is an engineer should pay more attention to in the modern society. To the engineer, as a designer, you should let your clients to accept your design, recognize that what you designed is the most suitable one in many possibilities; you should let the examiners and officers from government believe that your design accords with the low and specification so that the public and surroundings are safety? and you should let the contractors, manufacturers and construction companies understand your consideration and its rationality and feasibility. After being an engineer, you will find that you are frequently asked to attend meetings, to explain something for the project you designed, and you have to go to the construction site to hear new problems and tell the technician the answers. All of these need good communication unfortunately, until now our high schools and universities gave few chances to most of students to train their communication skills. Young engineering students now should take this seriously, and make great efforts to improve their communication ability.The basic element of communication is to speak. So try to look on your audience, no matter in seminars, in meetings or even in your friends' parties, make your voice loud, speak clearly and use plain but vivid vocabulary as possible.Besides speaking, the effective communication includes writing skill and expression of one's idea both in pictures and simple formulas. There are many skills you should learn, but the most important thing is to remember that the purpose of effective communication is for thoroughly understanding between you and your companion.Communication is not the same thing performing on a stage, where the key point should be exchange of information successfully. Good communication skill also includes hearing and considering companion's opinion. Discussion is also involved in the process of communication.2.4How Do You Match the Demands of the Program Education?Through four-year-period study to make yourselves acquire basic knowledge and training for being an engineer is one of the main targets that makes you enter into a university and enroll into a special engineering program.University is a new circumstance to freshmen students. For those who just left high school, and perhaps many of them are first time to sleep in dormitory of school, they should he familiar with the new life as early as possible.STUDY IN CLASSROOM: Needless to say, study is the most important task. There are many things to 'study'. However, to study and understand the knowledge which are necessary for the education objectives as introduced previously in this chapter and specified by the program, education plan is the basic requirement.As a student, you have had the school experience more than ten years, so you know the study skill well; reading textbooks, attending the lectures, taking noteswhen listening, doing homework ............... .. those are almost the same as in high schools. But something changes.The engineering students usually do not have their fixed classroom. They should move from one building to another during the ten minute break between classes. Nobody shares one standard curriculum schedule with his classmates in the same program, especially in the junior and senior year. Students have the opportunity to choose what they 'prefer', and every one shall type the number of the course he wants to join in the next semester into the computer registered system, or after a long queue outside the administration office to fill in course register form. To Chinese students, the most difference from the traditional high school is perhaps that no teacher will strictly monitor your daily study life.Are you free? Certainly. But, just to certain extentSame as the other programs, the Civil Engineering Program requires necessary credits before you are approved to graduate from the university. Each course has its credits according to the class hours and the importance. After passing the examination, you can obtain the pointed credits. If the program asks its students to fulfill total 150 credits, you will never expect to be awarded the engineering bachelor degree in the case that you earned only 149 credits! Furthermore, as you have known, the courses you have to take are divided into three types, requirements, approval electives and free choice, but to each of the three types, the program education plan specifies a certain amount of credits you have to obtain. That is to say your freedom is not infinite.Sometimes, a student will be informed that he did not meet the requirement of the program because he does not pick enough credits in approval electives indicated by the program education plan. So, students had better to read program education plan and student manual carefully once enrolling in the program, and to follow it in the following days. What your tutor who is designated by the department for you, if any can do is to give you some suggestion or advice when you consider to choosesomething.To finish all the courses the program asks is important, and to get high points is encouraged. When you pursue advanced degree study, or apply for a good position1)i n your career life after graduation, high points are always helpful at the beginning. However, good students are not those who only know the description printed on the books or recite the formulae, but fail to explain practical phenomenon,to discover unknown things and to have strong motivation to create new knowledge himself. So university professors encourage students to consider problems in different views, and appreciate students to observe in their own eyes and to ask questions after thinking.JOIN ACTIVITIES IN CAMPUS OUT OF CLASS ACTIVELY: Since an engineer needs to learn effective communication with others and smooth cooperation with work teams, and to be a good fellow and a success leader both in engineering and social activities, engineering students ought not to localize their 'study' only in academy or pure specialty. Fortunately, a university is such a school that provides with plenty of opportunities to those who would like to develop their multi-talents so that campus activities are called the 'amateurish classroom'. To join one or several activities which attract you in variety of campus activities, i.e. sports, drama and concerts, forums, competitions, clubs and reading party, will benefit your spirits and brain, enlarge your friend circle and get a way more comfortable to develop yourself. It is the university tradition to encourage students to join campus activities.PERSIST IN PHYSICAL EXERCISE: It is not a special requirement to civil engineering program students. Keeping in good health makes people to have confidence to live and work, to ensure the engineers energetically devote themselves into heavy work. By the way, though it is said not to work too heavy, in fact the work of civil engineers is really a heavy one, considering the duty engineer must take for the safety of human being and the society!Universities seek two main achievements in this aspect: to let the daily physical exercise become one of the personal customs of students and to train students to have some basic skills for physical exercise. Both of these are indispensable preparation for a qualified engineer.BE AWARE OF SOCIAL RESPOSSIBILITY:了解社会责任Why has society established a register engineer system, and why has this system been widely accepted by most of the industrial countries? The answer is that each engineering project that engineers involved in is not only a solution to a pure technical problem. At first, it will relate to the safety of life and estate. The failure of a building, collapse of a bridge or even a serious accident when undergoing construction may induce a real catastrophe to people, and make the loss of life and estate. So society asks that engineers who take the technical responsibility to the projects must be those who are qualified in knowledge and abilities. The procedure to cognize the candidate's qualification in engineering is the matter of register engineer system.With the development of natural and social science, people have more comprehensive understanding to human being and the relation with the world. In such a background, engineers should consider more and take larger responsibilities. The engineers are being required to understand the relation of his engineering projects with the society, and the。

Unit 4 FoundationFoundations are bases placed on the ground so as to spread a vertical load over it.Bases,which carry horizontal load,are usually called abutments.Foundation may be built in one of many different materials.It may be of timber or of steel joints encased in concrete, of reinforced concrete(r.C.)or plain concrete without reinforcement.Structures built on strong rock generally need no foundation since rock is usually as strong as concrete,and goes much deeper.All that is needed on rock is a little concrete or mortar to make the surface 1evel.One of the commonest foundations in the civil projects is that for a concrete column or a steel stanchion.It is generally designed for the same maximum load as the column,and usually is an independent foundation.Where the pads in one row become large that they nearly touch,it is convenient to join them into a continuous(or strip)foundation,which generally will be cheaper to dig and to concrete than the same foundations built separately as pads.Combined footings are those in which the would be so large that they nearly meet,but unlike strip footings.they may carry the load from more than one row of columns.The final development of the combined footing is the raft foundation in which all the pads are combined into one reinforced concrete slab,which may vary in thickness,but is usually same thickness throughout its area.The design of a multi-story building on compressible soil is difficult and therefore extremely interesting.Compressible soils are like a sponge,sinking most where the pressure is greatest and the load is largest.Thus even if all the foundations are designed for the same bearing pressure,say l ton/square meter,the largest foundation will sink the most because it has the largest load.A correct foundation design will therefore apply a higher bearing pressure to the smaller foundations and a lower one to the larger foundations.The exact calculation of this different bearing pressure is extremely difficult.But at least this is now the aim of foundation designers.It must be pointed out that the foundation designer should know the safe bearing pressures,which are advisable at every level possible for the foundation before he starts the design.He will get these figures from the organization which makes the soil mechanics survey for the site.For most multi-story buildings.the structure itself is in a very early stage of design at a time when the foundation must be designed very quickly.The building design must,however,have progressed so far that,at least,the positions of the columns should be known,and therefore.the floor spans will be fixed.Then thefloor thickness can be worked out.This will vary only slightly if at all from floor to floor,and it must be calculated as closely as possible including the topping.Generally.an allowance of 13cm of dense concrete will be enough,plus 5cm for the topping and the floor surface,making 18cm in a11.The weights of the beams,columns and stairs can be regarded as included in the floor thickness allowance.If the floors are to be built with hollow tiles or with lightweight aggregate,a reduction for this should be made.Isolated columns or stanchions are normally supported on square concrete foundation bases.Where such columns are spaced at close intervals,it is often more practical to provide a continuous concrete strip foundation to carry a complete row,as is done for load bearing walls.Concrete foundations need not always be reinforced.but where the load to be carded is high and the bearing capacity of the soil poor,heavy reinforcement is usually necessary.Where the bearing capacity is particularly poor or the quality of the soil varies considerably, a raft foundation is often recommended to support normal buildings.This type of foundation simply consists of a reinforced concrete slab,on which the walls are built.For heavy multi-story blocks built on poor soil, the foundation often consists of a watertight reinforced concrete open box,which also forms the basement.When a foundation is laid in poor soil,it is necessary to excavate to a greater depth than normal to reach a solid base.If a good base cannot be found at a reasonable depth,then a so-called deep foundation must be provided.This usually comprises a series of driven or cast-in-situ reinforced concrete piles.New Wordsfoundation n.基础spread V.分布,传播abutment n.拱座timber n.木材joint n.接缝:组件encase v.埋入reinforce v.加强column n.柱子stanchion n.柱子pad n.基座row n.排。

PartⅡ

Reading and Translating Passage A



Foundation Construction 基础 The purpose of a foundation is to carry the load of a structure and spread it over a greater area, evenly and without undue settlement, to the ground beneath. The size and type of foundation depends on the nature of the ground and the load carried by it. The bearing capacity of a soil means the maximum load per unit area (usually in terms of KN/M2)which the ground will safely support. 翻译: 基础的作用是承受结构的荷载,并将其均匀地向更大更深 的范围传递,避免不均匀的沉降。基础的尺寸和类型取决 于地基的自然状况以及地基所承受的荷载。土体的承载力 即是单位面积上地基所能安全承受的最大荷载。

句型:

1.The purpose of …is…:…作用是… 2….means……:指的是…..


As the nature of the soil often varies considerably on the same construction site, the capacity of the soil to support loads also varies. Therefore, it is not always possible to provide a uniform size of foundation for the entire structure, even if it may support a uniform load. To improve the bearing capacity in varying ground conditions, soft spots are usually filled with consolidated hardcore or a weak concrete, before the foundation is laid. 翻译: 即便在同一施工场地,由于地基的性质有很大差异,土体 的承载力也不相同。所以,即使基础能承受相同的荷载, 要为整个结构设计出相同尺寸的基础并不总是可能的。为 了在不同的地基条件下提高基础的承载力,在浇注基础前, 通常用碎石垫层加固或用强度低的混凝土来填充土质松软 的地方。

A foundation normally consists of either plain or reinforced concrete, which should be laid sufficiently below the ground frost level to avoid the possible danger of frozen soil lifting it. Fig.1 shows a plain concrete foundation to main walling, and Fig. 2 a reinforced concrete foundation to an isolated pier. 翻译: 基础通常有素混凝土和钢筋混凝土两种类型。基 础底面应设置于冻结线以下,以避免冻土会将其 顶起。图1是承重墙下面素混凝土基础的示意图, 图2为独立柱下的钢筋混凝土基础的示意图。
