Abstract：Research purposes ： Taking the effect of horizontal seismic action on the structure of underground station in Tianjin，the scientific method of structural seismic analysis， and how to take structural measures as the research purposes，the paper takes the Tianjin Metro Line 10 station for example， considers various load combinations of the structural use，uses the method of response displacement and time history analysis method for special seismic design.
Research conclusions: The results show that ： (1) The earthquake in Tianjin soft soil area is obvious，and the seismic action of soft soil is much larger than that of bedrock surface. (2) The structure of the underground station of Tianjin subway is considered as a flexible working stage. (3) Under the effect of the horizontal seismic force the structure form change of the standard two layer station and local three transfer station is in the most unfavorable position，the seismic condition may play a control role，so as to strengthen the weak component strength and improve the stmctural measures， and effectively improve the overall seismic perormance of subway station structure. (4) The research results can be applied to the seismic design of subway station structure in Tianjin area.
