摘　　要：本文结合我国首例将隔震技术应用于变电建筑物的工程———西安市330kV西北郊变电站110kV配电楼工程,研究隔震结构在多向地震作用下的非线性动力反应,并把计算结果与单向地震作用的结果进行分析比较。结果表明,本工程采用隔震技术是可行的,采用基础隔震措施可有效地控制结构的偏心扭转效应,使屋面层及楼面层的运动规律趋于一致,建筑物整体趋于平动,同时还可显著降低上部结构及电气设备的地震作用,并且在多向地震作用下的结果比单向地震作用时的隔震效果更加合理。目前该工程已竣工投产,本文工作将为隔震技术在电力系统的更广泛应用打下一个良好的基础。The nonlinear dynamic response analysis of isolated building subjected to multiple-dimensional earthquake action is studied for one 110kV switch building in 330kV Xibeijiao Substation, which is the first project using isolation technology in substation building. The results are compared with that of one-dimensional earthquake action and shown in this paper. The isolation technology can not only reduce the upper structure＇s eccentric torsion effect, which unifies the movements of the roof layer and the first floor and makes each section of whole building move together, but also decrease the earthquake action of upper structure and electric equipments inside the building obviously. Furthermore, the isolation effect under the condition of multiple-dimensional earthquake action is more reasonable than that of one-dimensional. So far, this project has been finished and the results in this paper will provide the basis of widely using the isolation technology in electric power system.
