摘　　要：现代桥梁往高墩大跨径方向发展,对结构的动力特性和抗震能力提出了越来越高的要求。矮塔斜拉桥在这方面的研究还较少,因此本文以某待建高墩大跨矮塔斜拉桥为例,应用反应谱法和时程分析法对其进行研究,供其他同类型项目参考。High Pier,long spans bridge is a very important trend in modern bridge.More and more requirements are put forward for the dynamic characteristics and seismic capacity of the structure.Few studies of extradosed bridge have been done in this area.Therefore,this paper takes an extradosed bridge with high pier,long span to be built as an example.Response spectrum method and time history analysis method are used to study it.A series of research results can be used for reference to similar bridges.

关 键 词：高墩大跨 矮塔斜拉桥 动力特性 抗震能力 反应谱分析法 时程分析法
