摘要

基于大变形和黏性边界条件,通过ANSYS有限元,建立了土-结构相互作用的二维动力模型,模拟了不同地震烈度、不同埋深、不同断面宽度条件下,富水软土地层地铁车站在地震荷载作用下的动力响应,分析了地铁车站压顶梁与车站顶板的相对位移反应、车站压顶梁内力,对地铁车站压顶梁设计提出了一些看法和对策。
In this paper,based on the boundary conditions of large deformation and viscosity,a two-dimensional dynamic model of soil-structure interaction is set up by ANSYS software.Then this paper uses the model to study the dynamic response of the water-rich soft soil metro station under seismic loads which is based on the different earthquake intensity,different depths as well as different cross-section width conditions.Further,this paper analyzes the relative displacement reaction between the copping beam and the station roof as well as the internal force of the copping beam.Finally this paper puts forward some ideas and countermeasures about the seismic design of the copping beam of the metro station.
