摘要

利用精确的土层和半空间动力刚度矩阵求解了含饱和土的层状场地的动力响应，给出了含饱和土层状场地的自由场（入射P波、SV波）、动力Green函数及刚性条形基础动力刚度的计算方法，由此建立的场地模型更接近实际情况。建议方法的退化结果与单相场地结果一致。研究了界面不同透水条件对基础动力刚度的影响，并与相应单相场地结果进行了对比。研究表明：界面透水条件对竖向弹簧系数影响最大，饱和土体中孔隙水对场地动力响应具有不可忽视的影响。

Abstract

Dynamic responses of a multilayered site with saturated soils are computed by using the exact dynamic-stiffness matrix of layer and halfspace. The calculations of free field response (incident P and SV waves)

Green’s functions and dynamic stiffness of strip rigid foundation are presented. The site model is more close to the real site. The degenerated results of this study are coincided with that of dry site. The influences of permeability of saturated soil on the dynamic stiffness of foundation are studied; and the results are compared to that of the corresponding dry site. The numerical studies indicate that the permeability conditions have an significant influence on vertical spring coefficients. It is shown that the porous fluid plays an important role in dynamic response of multilayered site with saturated soils.
