摘要

为了研究梁式桥的震害及其影响因素,基于近年来国内外几次大地震中梁式桥震害调查资料,对梁式桥震害现象进行分类并分析其原因,从地震烈度、建设年代、结构体系、地震次生地质灾害等4个方面对桥梁震害的影响分别进行了分析,得到了关于梁式桥地震破坏影响因素、破坏机理等方面的认识。
In order to study seismic damage and its influence factors of girder bridges,based on investigation data of girder bridge damages in several large domestic and foreign earthquakes,the seismic damage phenomena are analogized and the reasons are analyzed. Influence of some factors on the bridge damage is analyzed in more than 4 aspects as seismic intensity,construction time,structural system,secondary geological disasters and so on. Recognition in influence factors on seismic damage and damage mechanism of girder bridges is obtained.
