| Abstract: |
The Zhangjinggao Yangtze River Bridge currently under construction is located in the lower reach of the Yangtze River in Jiangsu Province, China, connecting the cities of Zhangjiagang, Jingjiang, and Rugao. It consists of two river-crossing bridges, one on the south channel and the other on the north channel of the Yangtze river. The south channel bridge is a double-span suspension bridge. In order to minimize the impact of bridge construction on the water traffic and the ecological environment of the Yangtze River, the beam span layout is designed to be 2300 m +717 m, and the cable span layout is 660 m + 2300 m+ 1220 m. When the construction is completed, it will become the world's longest span bridge, which is a veritable world-class mega structure. Since the bridge span breaks the records of all the existing bridges in the world, there is no standard to refer to and no experience to learn from. In order to solve the technical problems brought by the mega long span, the project construction team has utilized technological innovations, proposed six new world concepts, and therefore set six world records. |
