摘　　要：基于现行《建筑抗震设计规范》和《隔震规程》的相关规定,对新疆某一建筑面积为27128m2大底盘三塔楼结构进行隔震设计,采用动力时程分析方法,分析结构在设防烈度下中震及大震作用下的结构地震响应,验算了的隔震层的抗风承载力、隔震支座的竖向承载力及在大震下的隔震层的位移、抗倾覆能力等设计要点,并对该实际工程隔震设计中所遇到的问题进行分析和讨论。验算结果表明隔震设计满足现有国内外规范规程的相关规定,可供类似的工程背景的隔震设计参考。Based on the relevant provisions of Code for seismic design of buildings and isolation procedures. The dynamic time - history analysis method is a- dopted to design a structure with three towers with isolation in Xinjiang. And then it analyzes the structure response in fortification earthquake and seldom - occurred earthquake under fortification intensity. Checking wind capacity of the isolation layer, bearing vertical capacity, displacement of isolation layer, struc- tural resisting overturning ability and other design points under rare earthquake, the practical engineering＇ s seismic isolation design problems are analyzed and discussed. After designeheek, structure isolation design meet current seismic design specification , the design offers reference for similar engineering applica- tions.
