【摘要】 针对斜拉桥这种桥型在我国桥梁建设中得到大量应用的现状,以及近年来频繁发生的地震灾害,以国内某一混凝土斜拉桥为例,分析比较了不同结构体系斜拉桥的地震响应特点,总结了斜拉桥的主要震害形式以及特点,分析了国内几座大跨径斜拉桥的抗震设计方法和性能要求,在此基础上归纳出了斜拉桥抗震设计的基本原则和标准,为我国同类型斜拉桥的抗震设计提供一些思路和建议.更多还原

【Abstract】 Based on the actuality the cable-stayed bridges are used widely in China and the earthquake happened frequently in recent years.A real cable-stayed bridge is chosen as an example,The characterizes of seismic response of cable-stayed bridge were firstly collected and seismic failure of cable-stayed bridge were investigated,seismic design theory of several cable-stayed bridge were compared in detail.And then seismic principle for cable-stayed bridge was discussed,which all are referenced for design of new cable-stayed bridge.更多还原
