摘　　要：针对该车站地区的水文条件,在考虑地质水文地震效应的基础上,采用Midas GTS NX建立有限元模型,根据具体工程概况,运用地层-结构模型的三维有限元数值模拟方法对地铁车站标准段进行特征值和时程分析,得出车站的位移、弯矩、剪力,柱的弯矩、剪力、位移和轴力,根据相关标准和国家规定,得出车站的抗震分析结果,为地下车站的抗震分析提供支持。Based on the hydrological conditions of the station area and considering the geological,hydrological,and seismic effects,a finite element model was established using the Midas GTS NX module.According to the specific engineering situation,the three-dimensional finite element numerical simulation method of the stratum structure model was used to analyze the characteristic values and time history of the standard section of the subway station.The displacement,bending moment,shear force,column bending moment,shear force,displacement,and axial force of the station were obtained.According to relevant standards and national regulations,the seismic analysis results of the station were obtained,providing support for the seismic analysis of underground stations.
