摘　　要：本文简要介绍了改性沥青阻尼垫(SBS)与约束砂垫层两种隔震方法隔震的原理,及其在平湖市广陈镇农村抗震设防示范工程中的应用情况。进行了振动台模型试验,以及对试点建筑人工激振的响应测试。模型试验结果与人工激振响应实测结果表明,本方法隔震效果良好,而且减震效果随着地震动加速度的增加而改善,因此对"大震不倒"这一目标具有更好的设防效果。In this paper,the principle of isolation with modified asphalt damping cushion and constrained sand cushion and its application in the earthquake resistant protection rural project of Guangchen town are introduced briefly.Besides,the shaking table model tests and the response tests of the pilot building by artificial excitation are conducted.The test results show that the isolation effect is favorable and the damping effect is better with the increasing of seismic acceleration.Therefore,they have better fortification effect to no collapsing under strong earthquake.
