摘　　要：对某8度设防烈度区的某混合结构进行基础隔震分析与研究,隔震层选用弹性滑板支座、铅芯橡胶支座以及天然橡胶支座三种支座组合,以期达到较好的隔震效果。分析表明:采取弹性滑板支座组合隔震可以有效降低上部结构地震响应,满足隔震要求,同时结构位移也能控制在允许范围内。The base isolation technology was applied for the design located at the area assessed as intensity of eight degrees. The isolation ing bearings of an asymmetric hybrid structure layer is composed of elastic slid- , linear rubber bearings and lead rubber bearings to achieve a better isolation effect. The analysis shows that the combination of elastic skid support can effectively reduce the seismic response of the upper structure and meet the isolation requirements, and the structural displacement can be controlled within the allowable range.
