【摘要】 利用ANSYS对北京某明挖地铁车站在水平地震波作用下的响应进行分析。建立土体与地下结构的相互作用模型,周边采用黏弹性人工边界模拟远地场,选用三种不同地震波对地铁车站进行了时程分析,同时分析埋深对车站地震响应的影响。计算结果表明,地震波的种类和埋深对地下结构地震响应影响较大。更多还原

【Abstract】 The aseismatic capacity of an open-cut subway station structure in Beijing under the action of horizontal earthquake wave is analyzed and calculated using ANSYS,on the boundary of the separate soil-underground structural interaction system,damp springs are established to simulate stratum continuum.Different earthquake instensity and embeded depths are considered in the time-history analysis,It is demonstrated that type of earthquake wave and embeded depth have great effects on the seismic response of underground structure.更多还原
