［摘要］以砂與橡膠粒隔震墊層作為研究對(duì)象，通過(guò)振動(dòng)臺(tái)模擬試驗(yàn)，分析在不同石英砂粒徑、墊層厚度和橡膠粒含量的條件下結(jié)構(gòu)的隔震情況，以研究砂與橡膠粒隔震墊層的減震效果。結(jié)果表明，粒徑大的石英砂隔震墊層的減震效果好；墊層厚度的增加對(duì)減小結(jié)構(gòu)各個(gè)樓層加速度是有益的；當(dāng)橡膠粒在混合材料中的含量增加時(shí)，結(jié)構(gòu)各個(gè)樓層的加速度反應(yīng)呈減小的趨勢(shì)。

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
