摘　　要：近期在智利圣地亚哥召开的第16届世界地震工程大会汇集了世界地震工程领域最新研究成果,有关桥梁抗震研究方面的论文就有90多篇,主要涉及大跨度桥梁的抗震设计、基于地震可恢复性的桥梁减震隔震措施、桥墩的抗震性能研究、桥梁的碰撞与接触问题、桥梁的地震反应分析等方面的内容。本文就这些方面的内容进行分类汇总和介绍,并谈了几点体会。很显然,桥梁抗震研究的发展趋势也会与整个地震工程界倡导的可恢复性的抗震设计理念同步,在可方便替换"保险丝"构件、摇摆自复位体系、更有效的减震隔震措施等方面有所推进。从大会报告的内容看,减隔震装置和桥墩自复位体系都是当前桥梁抗震研究的热点课题,如果将两者同时用于桥梁体系,进行优化设计,会有更好的抗震效果。The 16th World Earthquake Engineering Conference, recently held in Santiago, Chile, brings together the latest research in the world＇s seismic engineering field. There arc more than 90 papers talked about the seismic research on bridge, which include the seismic design for long span bridge, resilience by design and anti-seismic system, the seismic performance of bridge piers, pounding and contact problem of bridge, the earthquake response analysis of bridges etc. This paper first summarizes and introduces the content of bridge seismic research. And then the experience of recent research progress in the field was talked about. It is clear that the development trend of bridge seismic research will also be synchronized with the seismic engineering community to promote the resilience of seismic design concept. It is going to be developed in the replaceable ＂fuse＂ components, the self-centering sys- tem, and isolation system. From the contents of the report, the anti-seismic system and the self-centering system of the pier are the hot topics of the current seismic research of the bridge. If the two are used for the optimized design of the bridge system at the same time, there may be better seismic effect.
