[摘要]  本文针对地铁车辆段上部空间开发过程中遇到的刚度和质量突变问题，引入层间隔震技术，并采用ETABS建立层间隔震结构的模型进行时程分析，得出结构在地震作用下的周期、层间剪力和层间位移，并与未采用层间隔震技术的抗震结构进行对比，结果表明层间隔震结构的减震效果非常明显，地铁车辆段上部空间开发中可考虑采用。

Abstract: In this paper, the story isolation technology is applied as the earthquake-resistant of this structure is greatly weak-ended for the sudden change of stiffness and quality in exploitation of the land above the platform of the subway depot. By using ETABS, the dynamic time-history analysis of isolation structure is carried out. the seismic responses of the structure, including the periods, shear force and displacements of each floor, are calculated and compared with those of the same structure without isolation, to assess the damping effect of the story isolation structure, some useful conclusions are obtained.

Keywords: subway depot; story isolation ; time history analysis; seismic response
