中文摘要：

利用有限元方法，将隔震结构、基础和土体作为一个整体系统进行分析，研究了不同土性土-结构相互作用对基底地震动输入和隔震体系动力特性与地震响应的影响。分析结果表明，土-结构相互作用对基础隔震结构存在影响，因而在工程设计中，隔震结构不应忽略土-结构相互作用效应的影响。

英文摘要：

This paper proposes a way to analyze the base isolated structure , foundation and soil mass as a whole system by means of the finite element methods, the effect of soil - structure interaction （SSI） with various soils on the seismic input of the foundation, the dynamic characteristics and seismic response of the isolation system are studied. The results indicate that SSI has an influence on base isolated structure and in engineering design of isola- ted structure, designers should not ignore the influence of SSI effect.
