［摘要］以砂与橡胶粒隔震垫层作为研究对象，通过振动台模拟试验，分析在不同石英砂粒径、垫层厚度和橡胶粒含量的条件下结构的隔震情况，以研究砂与橡胶粒隔震垫层的减震效果。结果表明，粒径大的石英砂隔震垫层的减震效果好；垫层厚度的增加对减小结构各个楼层加速度是有益的；当橡胶粒在混合材料中的含量增加时，结构各个楼层的加速度反应呈减小的趋势。

Abstract: Based on the sand and rubber particle vibration isolation cushion as research object, in order to study the vibration-suppressed effect of sand and rubber particle vibration isolation cushion, simulation experiments on the shaking table were carried out to evaluate the isolation of the structure under different conditions including the size of silica sand particle, the thickness of cushion and the rubber particle content. The result indicates that the vibration isdution cushion with the silica sand of big size has better vibration isolation effect; it’s useful to decrease the acceleration of each floor of the structure when the thickness of the cushion increases. The acceleration of each floor of the structure would decrease if the rubber particle content in the whole composition increases.

Keywords: sand and rubber particle; isolated structure; shaking table
