摘　　要：昆明天湖景秀项目百米高层剪力墙结构住宅采用基础隔震技术,通过铅锌隔震支座和普通橡胶隔震支座的合理布置和设计,取得了良好的隔震效果。对隔震系统偏心率、楼层最小剪力系数、各设防水准支座应力、大震下变形和恢复能力、抗风设计等做了详细分析。采取单向和三向非线性时程分析进行大震包络设计,对重点楼层位移和受拉支座应力进行了重点讨论。针对高层结构隔震设计,归纳了隔震支座的布置原则,提供了实用的设计流程,供工程参考。The base isolation technology was applied to a 100-meter-high shear wall residential building of Tianhu Jingxiu project in Kunming,both lead rubber bearings and rubber bearings are set on the right location,in order to obviously decrease seismic response of upper structure.The isolation layer eccentricity,the minimum seismic shear coefficient,the tension and compression stress and lateral deformation of isolator under all seismic levers,and wind resistance capacity were detailed analyzed.Both one-dimensional and three-dimensional finite-element model were applied for nonlinear time-history analysis and envelope design,the deformation of key storeys and tension stress of isolator were discussed in detail.The key issues of isolation design for high-rise buildings,such as isolators arrangement and isolation effect,isolation analysis process and results were provided the reference for project.
