【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。
[Abstract]:The 16th World Conference on Seismic Engineering, held recently in Santiago, Chile, gathered the latest research results in the field of seismic engineering in the world. There are more than 90 papers on seismic research of bridges, mainly on the seismic design of long-span bridges. Based on seismic recoverable seismic isolation measures, seismic performance of pier, collision and contact of bridge, seismic response analysis of bridge, etc. This article carries on the classification summary and the introduction to these aspects, and has discussed several experiences. Obviously, the development trend of seismic research of bridges will also synchronize with the recoverable seismic design concept advocated by the whole seismic engineering field, which can easily replace the "fuse" components and swing the self-reset system. More effective seismic isolation measures and other aspects have been promoted. From the content of the report of the Congress, both the isolation device and the bridge pier self-reset system are hot topics in the seismic research of bridges at present. If they are used in the bridge system at the same time, the optimum design will have better seismic effect.
