桥梁抗震设计探析

结合汶川地震桥梁损害,强调桥梁抗震设计应坚持"最强设计原则",对地震造成的上部结构、支座、下部结构、基础损害及震后次生灾害引起的桥梁损坏进行了分析,并提出了相应的对策措施,同时将部分措施应用到山西省繁峙至大营高速公路桥梁的抗震设计中。

Discussion on Bridge Seismic Design

That bridge seismic design should insist strongest design principles is emphasized combining with the bridge damages in Wenchuan earthquake.Damages to superstructure,support,substructure and foundation caused by earthquake and bridge damage caused by post-earthquake secondary disaster are analyzed,and corresponding countermeasures are proposed.Meanwhile,some of the measures are used in seismic design of the expressway bridge from Fanshi to Daying of Shanxi.
