摘　　要：在地基与基础之间设置砂垫层来达到隔震和减震的目的,是建筑物隔震、减震技术研究的新领域。对地震波波形、地震波谱特性、人工波三种情况分别进行了研究,得到相应的反应谱;砂垫层剪切波速、砂垫层厚度与最大加速度的关系曲线;砂垫层刚度不同时、砂垫层厚度不同时的加速度反应谱,以期完善该理论。Earthquakes occur in China frequently, and many are in the countryside or towns. Now there are many brick-and-concrete composite constructions or brick-and-timber constructions in the countryside and the towns, and they will still be major styles in future. So, it is necessary for these buildings to study seismic response. Sand cushion between foundation and soil can reduce the calamities caused by earthquakes. Sand cushion at input different peak value results different seismic response. The calculations of sand cushion can prove it.
