摘要
采用基于波传播理论的结构分析直接刚度法,分析了SH波入射时,土层性质对刚度增长场地、含刚性土层场地和含软弱土层场地放大效应的影响.得出的结论可帮助提前预估自由场地的地震反应.
By means of the direct-stiffness method of structural analysis based on the theory of wave propagation, the influence of properties of soil layer on the amplification effect for the incident SH waves of a site with increasing stiffness, site with stiffness layer and site with soft layer is analyzed. The conclusion can help furecast the result of response of a free-field to earthquake.
