某扭索面独塔斜拉桥总体设计

Overall design of a single tower cable-stayed bridge

以某扭索面独塔斜拉桥为工程背景,介绍了该类型桥梁的总体设计思路及重难点设计。通过合理的总体布置及细节设计,并结合数值模拟分析进行设计优化,对扭索面钢梁钢塔斜拉桥的设计可提供参考。

Taking a single-tower cable-stayed bridge with a guilloche plane as a project in Beijing,the overall design ideas and important and difficult points of this type of bridge are introduced. Through reasonable overall layout and detailed design,combined with numerical simulation analysis to optimize the design,it can provide reference for the design of the cable-stayed bridge with steel beam and steel tower with twisted cable surface.
