摘　　要：工程中常见的地基往往含有多个夹层,文中将各个夹层按力学性质进行分组,分别考虑了各级夹层对整个地基本构关系的影响,得出了含有若干夹层地基的本构方程,为求解夹层地基的本构关系的研究提供了新的思路。利用本文中的理论可反求横观各向同性地基的弹性参数,并可考虑地基的弹性参数随深度变化的情况对整个地基的本构关系的影响。There are several sandwiches in the foundation of engineering.In this paper, the sandwiches are divided into groups according to their mechanical properties,and the constitutive equation of the foundation with sandwiches is derived,which gives new ideas to the study on the constitutive relation of the foundation with sandwiches.

关 键 词：夹层地基 本构方程 弹性矩阵
