基于ABAQUS的水平成层场地地震反应无限元分析

摘要

地下结构的抗震研究是当今地震工程界的重要研究方向之一，其研究方法与地面结构相比有较大的不同．本文基于动力无限元分析理论，利用ABAQUS软件的动力时程分析结合无限元边界实现了一雏岩体的地震动响应分析，进而同基于SHAKE程序进行的一维土体地震动反应分析结果作了对比，说明在ABAQUS软件中实现的一维岩体动力反应分析方法是具有较好精度和易用性的．%Seismic research of the underground structures is the main research orientation in the seismic engineering circle. In this paper, the method of dynamical time-history analysis in ABAQUS combined with infinite element boundary is used to analyse the seismic response of One-dimensional Rock Mass. Then, by comparing the calculation of the seismic response of One-dimensional Rock Mass with the results based on SHAKE, we can verify that the method based on ABAQUS is reliable and the better simulation precision can be achieved.
