摘　　要：工程中常见的地基往往含有多个夹层 ,将各个夹层按力学性质进行分组 ,分别考虑了各组夹层对整个地基本构关系的影响 ,得出了含有若干夹层的地基的本构方程 ,为求解夹层地基的本构关系的研究提供了新的思路。利用该理论可反求横观各向同性地基的弹性参数 。There are often some branching strata in the foundation soils of engineering.Through grouping the branching strata in mechanical property,and considering the influence of branching strata to the constitutive relationship of integral foundation soils,the constitutive equation of foundation soils with branching strata is obtained,which offers a new thinking way to solve the constitutive relationship of foundation soils with branching strata.By using the theory stated above,the elastic parameters of transverse isotropic foundation soils can be obtained considering the varity of elastic parameter with depth.

关 键 词：夹层地基 本构方程 弹性矩阵
