摘要: 对某一大跨度桥梁桥址处地质、地形等局部场地进行模拟及地震反应分析,得出桥梁各个支撑处的地震动参 数,再对桥梁进行多点激励地震反应分析,并将结果与一致地震动作用下的桥梁地震响应对比分析。考虑局部场地 效应的多点激励作用与一致激励作用下得出的桥梁地震响应有较大差异,并对倾斜岩面场地处的桥梁抗震设计提 出一些建议。

关键词: 桥梁地震反应分析, 地震动输入, 局部场地效应, 多点激励

Abstract: The local site of a long-span bridge was simulated and the seismic response of the local site was analyzed,thus the ground motion parameters of each pier were obtained. By using these parameters,the bridge multiple-incentive seismic analysis was carried out. Then the result was compared with the seismic response of the consistent input. Bridge seismic responses in the both cases were quite different. Some suggestions of the bridge seismic analysis were put forward.

Key words: bridge seismic response analysis, seismic input, local site effect, multi-support excitation
