| 摘 要： | 针对重庆鱼嘴长江大桥提出了斜拉桥和悬索桥两种不同设计方案，建立了空间杆系有限元模型，进行了结构动力特性分析和抗震性能验算，结果表明，在给定的地震动作用下，虽然该桥两种方案的地震反应均较小，不控制设计，但悬索桥方案在抗震性能方面优于斜拉桥。

| Abstract: | Two design proposals, one for a cable-stayed bridge and the other for a suspension bridge, are presented for the Yangtse River Bridge at Yuzui and the space member FE models for them are also built. The dynamic characteristics and anti-earthquake performance of them are analyzed. The results of the analyses show that the earthquake responses of two design proposals are both little and do not control the design. However, the suspension bridge proposal is better than that of the cable-stayed bridge in terms of their anti-earthquake performance. |
