World bridge history added & other

World bridge history added & other; Wuhan made & throughout; . After 5 years of construction, the world's first two span suspension bridge span more than 1000 meters of tower & ndash; & steel workshop; Jiangsu taizhou changjiang river highway bridge opened yesterday morning implementation and marked by the bridge bridge power into the power of our country. The bridge by the iron bridge surveydesigncourtdesignThe second shipping board of, in the China railway DaQiaoJu, and to build, was composed of wuhan for world QiaoLiangShi Bridges legion work again and again and again. Wuhan parrot chau Yangtze river bridge construction are also benefiting from the bridge design.

The world's first km level two span suspension bridge tower

Mention of suspension Bridges, citizens can be seen most often appears in the American film of the golden gate bridge. Completion of this bridge opened in 1937, colourful jing world, to become the world's QiaoLiangShi on a monument. Today, like the statue of liberty, golden gate bridge has become a symbol of the United States, one of the visitors each year more than 1 million people.

Structurally, the golden gate bridge for the two tower three span suspension bridge. After 70 years, the world's major rivers on suspension bridge are used for almost two bridge tower shape, or is a across two towers, either two tower three across two tower of wuhan yangluo changjiang river bridge is a suspension bridge across. Later, the bridgeThe designerOn the basis of the two towers, created the model of three towers, but its span are only a few hundred meters. Yesterday, jiangsu taizhou changjiang river highway bridge opened to traffic, broke the situation, created the five in the world, one of the most important one is that created two span suspension bridge tower of km level.

China engineering design masters, China railway bridge survey bureau chief engineer Gao Zongyu introduction, three tower suspension bridge was two tower suspension bridge mainspan set up in the middle of a new type structure of the main tower, compared with conventional two tower suspension bridge, the structure characteristics of significantly different, can greatly reduce the main cable and anchorage force on both ends. The tower structure used in large span suspension bridge, there is no ready-made experience on world QiaoLiangShi to follow.

Taizhou changjiang river highway bridge is located in the midsection of the Yangtze river in jiangsu province, have been built in jiangyin Yangtze river bridge and runyang Yangtze river bridge, a total investment of 9.37 billion yuan, two-way six lanes, design driving 100 km per hour. Its main USES two span suspension bridge tower. Among them, the two sides on the tower is located in the development, the tower is located in the river. The three towers formed between two span, span length of 1080 meters. Bridges in the world history, has realized the tower suspension bridge span from hundreds of meters to km breakthrough.

From design toThe construction of theDemonstrate the parrot chau bridge

Jiangsu taizhou Yangtze river bridge why to build two across the three towers, is to create new world record?

Hospital deputy chief engineer of the railway bridge and taizhou bridge superstructure design leader Wan Tian bartender says, are using type tower suspension bridge, is the need of bridge site.

In taizhou Yangtze river bridge on the bridge site, if the construction of the towers of suspension Bridges, so the mainspan span to reach more than two thousand meters, the span is too large, the cost is too high. Therefore, China railway bridge survey design according to the characteristics of the river section, the creation of the adjust measures to local conditions.

Taizhou Yangtze river bridge bridge river section is & other; W” Shape, the river on both sides of the middle and high, so in the middle of the two towers, adding another bridge tower, tower are squarely in & other; W” In the middle of the top, two side tower in & other; W” On both sides of the top, so that will be more than two thousand meters & other A cross & throughout; Divided into more than one thousand m & other; Two cross & throughout; .

Tower two cross has two advantages, one is to reduce the water piers and the number of anchorage structure, minimize the shoreline and channel resources utilization, convenient navigation under the bridge. The navigable clear height reached more than 50 meters, navigable clear width of 760 meters, can meet the needs of the 5 ton panama bulk carrier navigation. Second is to greatly reduce the stress of the main cable and anchorage, save the project cost.

Chinese master of engineering design, main technical institute deputy chief engineer of the railway bridge and the bridge head Xu Gongyi introduction, taizhou Yangtze river bridge construction and smooth traffic, solved a series of technical problems, provides the construction on the Yangtze river bridge a classic example, created a new situation. Wuhan parrot chau Yangtze river bridge under construction, from design to construction, are benefiting from taizhou Yangtze river bridge.

Wuhan parrot chau bridge in the river for & other W” Form, inspired by taizhou Yangtze river bridge, combined with the actual situation of hanyang, and wuchang, eventually adopted & other; Three towers SiKua & throughout; Modelling, in the middle of the main tower, tooThe steel workshop www.jingtabuilding.com. At present, the parrot chau bridge tower of two side has been completed, tower will recently completed, will come into a period of hanging line.
