岩石和岩体是一种多晶复合介质,由于不同类型的岩石(火成岩、沉积岩、变质岩)成岩过程存在本质差异,以及经受历次地质构造运动和地质外营力作用,所以,概括在“岩石”(或岩体)这一术语下的介质的力学性态就显得非常复杂. 众所周知,岩石和岩体具有以下构造与结构特征: 1、存在有晶体内陷和不同类型晶粒间的微空隙或微裂纹; 2、存在有原生的与次生的层理、节理、微裂隙或大裂隙;

Rocks and rock masses are polycrystalline composite media. Due to the fundamental differences in the diagenetic processes of different types of rocks (igneous rocks, sedimentary rocks, and metamorphic rocks), as well as the experiences of various geological tectonic movements and geological and external forces, they are summarized in “rocks”. The mechanics of the medium under the term “or rock mass” is very complicated. It is well known that rocks and rock masses have the following structural and structural features: 1. There are crystal intrusions and microvoids between different types of grains. Or micro-cracks; 2. There are primary and secondary bedding, joints, micro-fissures or large fissures;
