摘要

针对目前对大跨度斜拉桥抗震性能的研究多只以主桥为分析对象，而对斜拉桥与引桥之间碰撞问题的研究相对较少这一现象，以某九江大桥为例建立了斜拉桥与引桥之间的碰撞分析模型，分别对场地类型、斜拉桥重心高度和引桥结构形式等影响斜拉桥主桥与引桥之间碰撞效应的主要因素进行的系统分析，得到了一些有意义的结论，可为类似工程的抗震设计提供参考。

Abstract

the study of long span cable-stayed bridge seismic performance only takes main bridge as analysis object. There are few reports about the research of earthquake impact between cable-stayed bridge and approach-bridge. Take a Jiu-Jiang big bridge as example, the impact analysis model between cable-bridge and approach-bridge was built. The analysis about impact influence factors between cable-stayed bridge and approach-bridge was systematically studied. The influence factors include site-type, high of gravity center, approach-bridge structure form. Some significant conclusions are got. It can be taken as references for similar projects seismic designing.
