| 摘 要： | 视地基土为各向同性的弹性半空间，用弹簧-粘性阻尼器模拟土对结构的影响，将地震激励模拟为平稳随机过程，对基础隔震体系的随机响应进行了分析。分析结果表明，地基土的性质对隔震结构有直接影响，但其影响比非隔震结构小得多。

| Abstract: | With the impact of subsoil on structure modeled by a spring-viscous restraint, the random responses to earthquake of the base-isolated system is analyzed in this paper, with the earthquake excitation simulated as a smooth random process and the subsoil taken as an isotropic elastic semi-space. The influences of the site soil and damping of the isolating floor on structural responses to earthquake are discussed respectively. The result indicates that the properties of the subsoil have a direct impact on the isolated system, which is much smaller than that on the non-isolated system. |
