[摘要] 利用MSC.Marc建立土-地下結(jié)構(gòu)相互作用有限元模型，以土-地下結(jié)構(gòu)為研究對象，對水平地震作用下深埋地下結(jié)構(gòu)工況展開分析，研究了土-地下結(jié)構(gòu)的地震反應(yīng)規(guī)律，對地基土隨地表變化的加速度峰值、隨埋深變化的加速度峰值、地下結(jié)構(gòu)的加速度峰值、地下結(jié)構(gòu)的應(yīng)變進(jìn)行了具體分析；研究了三種埋深工況下地基土與結(jié)構(gòu)的地震反應(yīng)規(guī)律，經(jīng)過對比分析，證明地下結(jié)構(gòu)埋深越淺，地下結(jié)構(gòu)與土層的地震反應(yīng)越強(qiáng)烈。

Abstract：Based on soil- subway structure system, soil – underground structure interaction finite element model is established by MSC. Marc. The response of underground structure when embedded deeper under the action of the horizontal seismic is considered. Specific analysis the peak acceleration in different surface point and buried depth point, the peak acceleration of underground structure and the strain of underground structure; the response of soil and structure in three working conditions is discussed. Though comparative analysis, prove that the more shallow underground structure buried, the stronger underground structure and the soil layer seismic response.
Keywords：soil-underground structure, embedment depth, numerical analysis, seismic response
