Bridges are incredible structures that help us get from one place to another over water, valleys, or roads. Some bridges are so special and famous that people travel from all over just to see them! Let me tell you about a few of the most amazing bridges in the world.The Golden Gate Bridge in San Francisco, California is probably one of the most famous bridges ever. It's a bright reddish-orange color and stretches for 1.7 miles across the San Francisco Bay. This suspension bridge is held up by huge cables and towers reaching 746 feet high! When it opened in 1937, it was the longest and tallest suspension bridge in the world. On a clear day, you can see for miles from the bridge. It's an iconic symbol of San Francisco.Another incredibly long bridge is the Danyang-Kunshan Grand Bridge in China. At over 102 miles long, it's the longestbridge in the world! This giant bridge is part of a high-speed railway line connecting cities in China. Imagine taking a train ride across a bridge longer than the entire subway system of some cities! It stretches across rivers, marshes, and even goes over a huge lake.

关于桥梁的英语简介
BridgesBridges are among the most important, and often the most spectacular,of all civil engineering works. The imposing bridges that have survived from ancient times are arched structures of heavy masonry, usually stone dr brick..Herodotus,the greek historian of the fifth cenury B.C., however mentions a wooden bridges across the Euphrates River at Babylon. In rome, the bridge of Fabricis, built in 62B.C.and named for its engineer,still carries traffic across the ataiber River,asdoes the Sant′Angelo Bridge, built in about 136A.D.Both of these bridges, and many other Roman bridges,have a series of arches supported by heavy piers that extend down to bedrock. Ancient sources also mention pontoon bridegs, usually in connection with military operation.A pontoon is a hollow drum that can float; a series of pontoons anchored to a riverbed can support a oadway. The Incas of per-Columbian Peru built remarkable suspension bridges, supported by cables of natural fibers, that crossed many of the deep gorges in their monutainous country.The sudden expansion in transportation systems that began in tha eighteenth century,and still continues in our own day, has enormously increaed the need for bridges as a part of highways and railroad, Better understanding of the forces that are exerted on structures and the improved materials that became available in the nineteenth century have made it possible to build increasingly longer ang stronger bridges.With the ability to span greater distances,the damlike effect of masonry arch bridges with several heavy piers that ; block he flow of a stream can be largely eliminaed.The simplest type of span is a beam bridge,consisting of a rigid beam between two supports. Today most simple beam bridges are strengthened by a truss, which is based on the triangle. Diagonal bams that extend between the horizontal and vertical beams give support against both comperssion and tension. Many early truss bridges were built of wood; one that was eected across the Susquehanna River in Pennslvania in 1815 had a span of 110 meters. Iron and then steel were later used in the consruction of truss bridges, still further increasing their stength. Trusses are not only strong but also light, because all unnecessary material has been eliminated in their design.Another type of beam bridge is the cantilever, in which a horizontal beam extends beyond its support.Cantilever bridges, like tusses, had also been built before iron and steel became available. Most cantilever bridges have wo arms of truss structure that meet or support a section between them. Cantilevers enabled bridges.During the ninteenth century, cantilevers were frequently used to build railroad bridges.The Quebec Bridge, which crosses the St. lawrence River in Canada, is the longest cantilever bridge in the world, with a span of 540 meters. It was completed in 1917, and until 1919 it was the longest bridge of any type in the world.A third type of moder bridge is he steel arch bridge, which can carry a roadway either above or below its arch of steel beams. An arch exerts strong downward and diagonal thrusts, so the piers that support it must be especially strong. Probably the most famous steel arch bridge is the Sydeny H arbor Bridge in Australia, wih a span of 495 meters. The Bayonne Bidge between New Jersey and Staten Island in New York has a span one meter longer.Suspension bridges span even longer distance than other types of bridge. The longest bridge of any type is the Verrazano-Narrows Bridge in New York, with a span of 1,280 meters. The deck or roadway of a suspension bridge is suspended from steel cables are supported by massive towers. The first modern suspension bridges usedlinked chains made of wroughe iron. Some of them survived for many years, like one across the Danube River in Budapest, Hungary. It was completes in 1849 and destroyed during World War, nearly a hunded years later.When steel became available, cables of steel wires replaced chains of wrought iron. Several suspension bridges built in this manner collapsed, however, as a result of storms or the movement created by the rhythm of the loads moving across them. It was later discoversd that these failures were caused by the lack of truss supports for the deck. The first major cable-type suspension bridge to overcomg these faults was designed by John A.Roebling at Niagara Falls. Its span of 250 meters was strengthened by trusses between the two decks. Roebling also used stays, inclined cables that ran from the main supporting cables to the deck, to stabilize the bridge. Roebling went on to design the Brooklyn Bridge in New York, which was completed in 1883 by his son, George Washington Roebling. The Booklyn bridge, with a span of 486 meters, is one of he most important-and one of the most esthetically satisfying-bridges ever built. The mothod devised by the Roeblings for laying the Brooklyn Bridge is essentially the same technique used today.He evelopment of reinforces and prestressed concrete has given engineers other important materials for bridge building. Concrete has been used particularly for relatively short-span bridges that are a part of freeway system. These bridges often use precast concrete beams. Many arch bridges have also been constructed of concrete. Currently, the longest concrete arch bridge is the Gladesville Bridge in Sydney, Australia. It has a span of 305meters, and its deck is above the arch.This is another example of an esthetically pleasing bridge.Many bridge that pass over rivers or canals must be movable so that shipping can pass under them. One type is the lift bridge, with towers that can raise the entire span between them by means of counterbablances and electric motors. Another type is the swing or pivot bridge, which pivots the span on a pier so that the bridge can swing openn parallel to the river or canal.A third type is the bascule bridge, which has one or two arms that can open upward at an angle by means of counterweights. A bascule with one arm is a single-leaf bridge, and with two arms it is a double-leaf bridge.Bridge constuction can present extraordinry difficulties. Usually the foundations for the piers must rest on bedrock, and often under water. One technique for working in these conditions is by means of a cofferdam. Piles usully made of interlocking steel plates are driven into the water bed. The water is then pumped out from within the use area that been enclosed.Anpther tachnique is the use of the pneumatic caisson. The caisson is a huge cylinder with a bottom sdge that can cut into the water bed. When compressed air is pumped into it, the water is forced out. Caissons must be used with extreme care. For one thing, workers can only stay in the compression chamber for short periods of time. For another, if they come up to normal atmospheric pressure too rapidly, they are subject to the bends,or caisson disease as it is also called, which is a crippling or even fatal condition caused by excess niteogen in he blood. When the Eads Bridge across the Mississippi River at St.Louis was under construction between 1867and 1874,at a time when the danger of working in compressed air was not fully understood, fourteen deaths were caused by the bends.When extra strength is necessary in the piers, they are sometimes keyd into the bedock-that is, that are extended down into the bedrock. This method was used to build the piers for he Golden Gate Bridge in San Francisco, which is subject to strong tides and high winds,and is located in an earthquakezone. The drilling was carried out under water by deep-sea divers.Where bedrock cannot be reached, piles are driven into the water bed. T ody, the piles in construction are usually made of prestressed concrete beams. One ingenious technique,used for the T appan Zee Bridge across the Hudson River in New York, is to rest a hollow concrete box on top of a layer of piles. Whenthe box is pumped dry, it becomgs buoyant engough to support a large propotion of the weight of the bright of the bridge.Each type of bridge, indeed each individual bridge, presents special construction problem. With some truss bridge,the span is floated into possition after the piers have been erected and then raised into place by means of jacks or crames. Arch bridges can de constructed over a falsework, or temporary scaffolding. This method is usually employed with reinforced concrete arch bridges. With steel arches,however,a technique has been developed where by the finished sections are held in place by wires that supply a cantilever support. Cranes move along the tension in the cables increases.With suspension bridges, the foundations and the towers are built first. The foundation and the towers are built first. Then a cable is run form the anchorage concrete block in which the cable is fastened-up to the tower and across to the opposite tower and anchorage. A wheel that unwinds wire from a reel runs this cable. When the reel reaches the other side, anther wire is placed on it, and the wheel returns to its original position. When all the wires have been put in place ,anoth machine moves along the cable to compact and to bind them. Constryction begins on the deck when the cables are in place, with work progressing toward the middle from each end of the structure.Bridge design is probably the hardest brain work in civil engineering. Bridge designers have a long period of training, only the best of them succeed, and only a small fraction of the bridge they design are built. The time from the first proposal for a bridge to the provision of the money for its construction is usually long and many bridge have been built only after the beath of their designer. A fine bridge engineer, shirley smith, who was the contactor′agent for the Forth Road Bridge, has written very well about his love of bridge work in his book Great Bridges of the World.For those who work on the site, bridge is hard in other way. They cannot settle down in one house because they rarely work in one place for longer than a year or two, and the working site is usually unprotected and something dangerous.The builders of the Forth Road Bridge〈1965〉were particularly prould of the fact no lives were lost in spite of the heavy winds,the snow and the cold rain. Word on bridge foundations,usually in cofferdams and something in caissons under comperssed air has often caused loss of life.One of the most intersting recent birdges, which will remain for many years the world′ largest, if not its longest, is the Verrazano-Narrows Bridge, New York, compieted in 1964, a suspension bridge of 4,260ft main span, having six traffic lanes on each of its two deck. It is also probably one of the world′s highest bridges since its m ain span has to be 216ft above the shipping channel whiah is 2,00ft wide. Its capacity is estimated at 13 million vehicles in the first year, rising eventually to 48 million vehicles, and it cost some 324million dollars to build.The main parts of a suspension bridge are the deck, the two cables and many suspenders transferring the deck load to the cables, the towers over which the cables passand the anchorages on the two banks. The Narrows Bridge has four cables, two on each side. In a self-anchored suspension bridge thereare no anchorages, the two ends of the cables being tied to the shore ends of the bridge structure.Most road bridges have pies rising outof the valley, on which the girders rest, with a deck carried by the girders and a wearing surface on top of the deck. Railway bridges sometimes differ in the wearing surface being unnecessary and therefore left out completely, so that wearing surface being unnecessary and therefore left out completely, so that there are then gaps between the bridge beams.The clear span of a bridge is athe gap from the near edge of one pier to the near edge of the next. The effective span is the spacing between the centres of bridge piers. The span, which is large than the clear span, is used in the design of the girders. At each shore, every bridge has foundation called abutments,an abutment being a foundation which carries horizontal load.An interesting and economical bridge which has become popular in Europe in the last twenty years and was first used in Germany is called the cable cantilever or bridle chord bridge, though other names have been used for it. It is always of steel, and like the self-anchored suspension bridge it has two towers over which its cables pass. A bridge of this type was completed in 1965 over the river Usk at Newport,Monmouthshire,England〈Fig.26〉.The 150-metre main span is supported at twelve point by ropes from the two towers, making it into a 13-span continuous beam with twelve elastic internal supports and two rigid end supports. The complete esign was analysed by a strain energy method and the analysis was checked by a plastic model. The cables pass over towers 52m high and are anchored on the shore side to the concrete approach spans. The towers are hollow concrete boxsection and the concrete in them is never under under tension, the maximum compressive stress being 100kg/〈cm*cm〉.The test cubes taken from the concrete of the towers were specified to have a minimum strength of 400/〈cm*cm〉. At high tide, the least height under the dridge is 13m, and the tidal range is 9.2m at the bridge. The main girder on this bridge are steel welded section and were mard by barge to the site and joined thre into a continuous structure. Because of the support from the cables, the main girder depth is remarkably small, only 1.3.Highway bridges and railway bridges are designed for dead load, live load, impact, temperature stresses, wind load, traction and braking forces, and on curves also for centrifugal force. Railway bridges have to be designed also for nosing, a sideways force from the flanges of the engine wheels on to the rails at curves.Americans generally use either the short ton or the kip in their stress calculations, the short ton being 2,000 pounds, considerably less than the metric ton, and the kip or kilo-pound being 1,000 pound. The kip is very widely used in the United States and many British engineers also find it convenient for calculations. The long ton of 2,240 pounds used in Britain is about 17 kg larger than the metric ton.Proplem involving moving loads are conveniently solved by influence line, which are used in all countries of the world. Shear diagrams and bending moment diagrams or envelopes show the effect of shear or bending moment at all points along the bridge span, but an infulence line shows the effect, at one point, of a load placed at any point on the structure. The base length of an influence line is the same as that of a bending moment diagram so it is important to state on the diagram what it it,otherwise misunderstandings may occur.桥梁是最重要的，往往是最壮观的所有民用工程。

介绍桥的英文作文英文：Bridges are fascinating structures that connect two places over a body of water or a valley. They are essential for transportation and have been around for thousands of years. There are many different types of bridges, including suspension bridges, beam bridges, arch bridges, and cable-stayed bridges.Personally, I find suspension bridges to be the most impressive.

The bridge spans 1.7 miles and can withstand strong winds and earthquakes. It's a true engineering marvel.Another interesting type of bridge is the beam bridge. These bridges are simple in design and consist of a horizontal beam supported by two piers. They are commonlyused for short spans and are often found in rural areas. I remember crossing a beam bridge on a road trip through the countryside, and it was a bit nerve-wracking because the bridge felt so narrow.Bridges are not only functional but also beautiful. Many bridges around the world are famous landmarks and tourist attractions. For example, the Tower Bridge in London is an iconic symbol of the city, and the Charles Bridge in Prague is a popular spot for taking photos and enjoying the view.In conclusion, bridges are fascinating structures that serve an important purpose in connecting people and places. They come in many different forms and have been around for centuries.
