Abstract: Taking an underground station project as the engineering background，ABAQUS finite element software is used to analyze the key issues in the modeling, such as the numerical integration method, the constitutive relation of structural materials, the determination of boundary conditions, the selection and input of seismic waves, finally an appropriate 3D standard metro station calculation model is established. According to the baseline drift of seismic waves occurred in dynamical time-history analysis of ABAQUS, SeismoSignal software is used to correct the baseline. Through theoretical analysis, the dynamical time-history analysis of metro station with split column and frame column structure under bidirectional coupling seismic action is conducted respectively. The results show that under strong earthquake, the load capacity of split column structure is 16% less than that of frame columns, but the ductility of the former increases about 35%. In other words, the split column structure can change the force characteristics of the frame columns by losing some bearing capacity, thus greatly improves the ductility of the column.
