研究目的：本文以水平地震作用对天津地区地下车站结构的影响、结构抗震分析的科学方法以及如何采取构造措施为研究目的，通过以天津地铁10号线梅林路站为例，针对天津地区明挖地铁车站常见车站形式，考虑结构使用过程中可能出现的各种荷载组合，采用反应位移法和时程分析法进行专项抗震设计研究。研究结论：分析结果表明：（1）天津软土地区地震作用明显，软土较厚区域地震作用远大于基岩面较浅区域；（2）天津地铁地下车站结构在地震作用下，可以认为结构处于弹性工作阶段；（3）分析得出在水平地震力作用下标准两层车站和局部三层换乘车站结构形式变化处为最不利受力位置，抗震工况可能在此处起控制作用，从而采用针对性措施，如加强薄弱的构件强度和提高构件节点的构造措施，切实提高地铁车站结构的整体抗震性能；（4）本研究成果可应用于天津地区地下车站结构的抗震设计。

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 structural measures, and effectively improve the overall seismic performance of subway station structure.(4 )The research results can be applied to the seismic design of subway station structure in Tianjin area.
