摘要
桥梁在地震中的碰撞反应不容忽视,文章综述了国内外桥梁地震碰撞的模拟方法以及各种形式桥梁结构的地震碰撞近期研究进展,归纳了桥梁碰撞的条件和影响因素,介绍了减轻桥梁结构地震碰撞方法和防落梁措施的主要研究成果,并对桥梁地震碰撞反应的进一步研究作了展望。
The seismic collision response of bridge cannot be ignored. This paper reviews the recent study progress of bridge seismic collision simulation methods used in China and other countries and the seismic collision of various bridge structures, summarizes the conditions and influencing factors of bridge collision, introduces the alleviating seismic collision methods for bridge structures and main research results of beam falling prevention measures, and discusses the further study on bridge seismic collision response.
