摘    要:本文采用横观各向同性层状弹性模型模拟半空间之上的层状了,推导了在SH波入射时这种场地土的动力刚度矩阵及基岩输入运动时场地呼应的计算公式,算例表明,横观各向同性层状场地与各向同性层状了频谱特性有明显的区别,应当引起重视。

关 键 词:横观各向同性  弹性体  层状场地  SH波  土动力学

Abstract:A model of transversely isotropic elastic strata is used to simulate the soil layers situated on a helf space. The dynamic stiffness matrix of the strata and the formula to evaluate their response to incident SH waves are derived. The calculated results show that there are evident differences between the response Fourier spectra of these two models. More attention should be paid to these phenomena.
Keywords:Transversely isotropic elastic strata  Soil layers  Response Fourier spectra
