| 摘 要： | 考虑桩-土相互作用效应，建立了桩基结构地震响应分析的有限元计算模型，并在时域上进行了整体有限元数值计算。为便于进行对比分析，简要阐述了桩-士-结构地震响应分析的子结构方法。进而针对工程实例，分别采用整体有限元数值计算方法和子结构分析方法，对桩-土-结构体系的地震响应进行了对比计算和分析。研究表明，两种方法所得计算结果是基本一致的，从而，为桩基结构的抗震分析与工程设计提供了参考依据。

| Abstract: | A computational model for pile-supported structures, which can duly consider the pile-soil interaction effect, is established by use of the finite element method, and its numerical implementation is made in time domain, accordingly. For the convenience of comparative analysis, the substructure method for seismic response analysis of pile-soil-structure system is briefly presented. Then a comparative study is performed for an engineering example and it is shown that the results obtained by the finite element method is common with the computational results achieved by the substructure method. These numerical results and findings will offer instructive guideline for earthquake-resistant analysis and engineering design of the pile-supported structures in practice. |
