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.
In view of the current situation that such bridge type of cable-stayed bridge is widely used in bridge construction in our country and the frequent earthquake disasters in recent years, taking a certain concrete cable-stayed bridge as an example, the earthquakes of cable-stayed bridges with different structural systems are analyzed and compared Response characteristics of the cable-stayed bridge, summarized the main forms and characteristics of the cable-stayed bridge, analyzed the seismic design methods and performance requirements of several large-span cable-stayed bridges in China, and summarized the basic principles of seismic design of cable-stayed bridges And standards, provide some ideas and suggestions for the seismic design of the same type of cable-stayed bridges in our country.
