层间隔震技术在地铁车辆段大平台上部土地开发上的应用研究

Research on storey isolation technology applied to exploitation of the land above the platform of the car depot for Ba-wang-Fen subway

为开发北京地铁八王坟车辆段大平台上部空间,层间隔震技术被采用。通过非线性时程分析和模拟地震动振动台试验,研究了此层间隔震结构体系的抗震性能。研究结果表明采用隔震技术后,结构体系抗震性能得到很大提高,其地震响应满足规范要求。

the storey isolation technology is applied to exploitation of the land above the platform of the car depot for ba-wang-fen subway. To investigate the seismic performance of the isolated structural system, nonlinear time history analyses are accomplished and earthquake simulation experiments are conducted for the isolateol structural system. The research results are shown that the seismic performance of the structures can be enhanced significantly after the isolation technology being adopted, and then the seismic responses can meet the requirement of code for seismic design.
