摘　　要：采用大变形和粘性边界条件,建立土-结构相互作用的二维动力模型,对浅埋软土场地地铁车站地震荷载作用下的动力响应进行数值研究,分析了地铁车站结构的水平相对位移反应和加速度反应,研究了地铁车站结构的埋深对结构地震位移的影响,并对地震作用下对地铁车站结构的内力进行了比较分析,对地铁车站结构的抗震设计提出了一些看法和对策。Using the method of large deformation and viscous boundary, a two-dimensional calculation model based on soil-structure interaction is set up to analyse the seismic response of a shallow-buried subway station structure in soft soil. The horizontal relative displacement and acceleration responses of the subway station structure has been analyzed. Additionally, the influence of different burial depth of the subway station structure on seismic displacement is studied, and the maximum forces of the subway station structure under earthquakes are comparatively analysed. Some suggestions and measures are presented for the seismic design of the subway station structure.
