| 摘 要： | 以郑西客运专线灞河连续梁桥为工程背景,利用有限元通用软件对该桥建立有桩和无桩两种模型。分别就这两种模型进行模态分析,并输入顺桥向和横桥向地震波进行反应谱和时程分析。通过结果对比,证明在对该类采用摩擦桩基础的桥梁进行抗震分析时,应该考虑桩-土-结构相互作用,以使桥梁受力更接近实际情况。

| Abstract: | With continuous beam bridge across Babe River in Zhengzhou-Xi＇an Passenger Dedicated Line as engineering background,two models with pile and without pile are established for this bridge using finite element common software.Modal analysis is separately carried out for these two models,and response spectrum and time history analysis are carried out under longitudinal and horizontal earthquake wave.Through result comparison,it is proven that pile-soil structure interaction shall be considered in earthquake resistance analysis for such bridge with frictional pile foundation so that bridge stress is closer to practical situation. |

| Keywords: | pile-soil structure interaction continuous beam bridge modal analysis response spectrum analysis earthquake time history analysis |
