摘要
通过对地基土质从软到硬的三个阶段结构———地基动力相互作用体系振动台模型试验所取得数据的对比分析,讨论了不同土性地基对地震波传递的影响.表明地基土层对地震动的影响与场地土特性、地震动大小等有关,不一定是放大作用,也可能起滤波和隔震作用.
Through analyzing the data of a series of shaking table tests of dynamic soil-structure interaction (SSI) system with soft to hard soils, the transfer of earthquake wave in various ground soils is investigated. The transfer of earthquake wave in ground soil is related to soil characteristic, excitation magnitude, etc.. It is not always amplificatory, but likely to be filter and isolation.
