土体损伤理论是描述土体结构性问题的有力武器,土体损伤复合体理论是土体损伤理论的重要分支。通过对岩土损伤复合体理论的基本问题进行深入研究,获得的主要成果有:得出了岩土损伤体的应力应变合成合理模式,不能采用简单的并联假设或串联假设;基于损伤是能量耗散的不可逆过程,提出一个新的损伤变量和损伤演化方程;提出了基于岩土损伤复合体理论的一般本构模型,及其各向同性情况下的表达式。
Soil damage theory is a powerful weapon to describe soil structural problems. Soil damage complex theory is an important branch of soil damage theory. Through the further study on the basic problems of the complex theory of geotechnical damage, the main achievements obtained are as follows: the rational model of stress and strain synthesis for the geotechnical damage body is obtained, and simple parallel hypothesis or tandem assumption can not be used; A new damage variable and damage evolution equation are proposed, and a general constitutive model based on the composite theory of rock and soil damage and its expression in isotropic case are proposed.
