鉴定结构面的力学性质,是地质力学工作的基础和先行步骤,只有正确地鉴定结构面的力学性质,才能对构造体系作出中肯的分析,从而解决生产实践中提出的各种问题。一构造形迹与结构面我们在野外经常见到的岩层褶皱、断裂、节理、劈理等地质构造现象,都是岩石在地应力的长期作用下形成的各式各样永久形变的形象,并且留下来相对位移的踪迹。地质力学把这些形象和踪迹,叫做构造形迹。可见,构造形迹指的是次生构造,主要是岩块、地块中的各种形变现象。构造形迹的规模有大有小,大者如几十乃至几百公里的大型拗折、断裂带,小者如显微镜下所见矿物晶格受地应力作用而形成的某些联晶面、岩
Identifying the mechanical properties of the structural plane is the foundation and first step of the geomechanical work. Only when the mechanical properties of the structural plane are correctly identified can the pertinent analysis of the structural system be made to solve the various problems raised in the production practice. Structure Tectonic and Structural Surfaces Geological structures such as folds, fractures, joints, and cleavages that are commonly seen in the field are all images of various permanent deformations formed by the long-term stress of the rock and remain Down the relative displacement of the trail. Geomechanics to these images and traces, called the structural footprint. Can be seen that the tectonic footprint refers to the secondary structure, mainly rocks, plots of various deformations. Tectonic scale of large and small, large, such as tens or even hundreds of kilometers of large buckling, fracture zone, the smaller person, such as under the microscope, the crystalline lattice stress by the role of stress and the formation of some crystal surface, rock
