桥梁抗震设计关键点与减震、隔震设计的应用

Research on Key Points of Bridge Seismic Design and Application of Shock Absorption and Isolation Design

主要研究地震作用对公路桥梁结构的影响。从桥梁抗震设计关键点和减震、隔震设计两个方面进行分析,对国内部分桥梁在地震中的破坏形式做了总结,以此为基础介绍了桥梁不同部位相关的抗震设计和减震、隔震设计,并着重介绍了减震、隔震支座在抗震中设计发挥的作用。

This paper mainly studies the influence of earthquake on highway bridge structure, analyzes the key points of bridge seismic design and shock absorption and isolation design, and summarizes the damage forms of some domestic bridges in earthquake. Based on this,the seismic design and shock absorption and isolation design of different parts of the bridge are introduced, and the role of seismic isolation bearing in seismic is emphasized.
