【摘要】 某330kV变电站中的110kV配电楼位于8度地震设防区,为单层钢筋混凝土框架结构,局部二层。在地下室与上部结构之间设置隔震层。对隔震支座的选型、改型及布置方案进行了研究,并提出了有益的建议。配电楼主体结构空间模型的时程分析结果表明,采用隔震措施不但可以显著降低上部结构的地震反应,同时降低了其内电气设备的地震反应。该工程即将竣工并投入使用。该工程为隔震技术在电力系统的更广泛应用提供了一个良好的实例。更多还原

【Abstract】 The base isolation technology is firstly used in substation of switch building.The selection,remodeling and layout of the base isolation bearer of a switch building in Xi’an are researched,and some useful advices are given.The time history analysis results of the structural space model show that the earthquake responses of the upper structure and the electrical equipments inside the building are diminished remarkably.The research provides a goof base for the wide use of the isolation technology in electric system.更多还原
