Description
technical field [0001] The invention belongs to the technical field of rock mechanics, in particular to a double-roughness structural plane shear seepage test sealing mechanism and a method for using the same. Background technique [0002] The study of the shear-seepage characteristics of the rock structure plane is the basis for the study of major geological disasters, such as earthquakes, landslides, etc. down the tunnel, etc. At present, the experimental research on the shear seepage of rock structural planes is to study a single structural plane. However, there are a large number of structural planes in the actual rock mass. Therefore, the research on the shear and seepage characteristics of the double-roughness structural plane is carried out in the laboratory to analyze the mechanical properties of the rock structural plane, the failure mode of the structural plane, the seepage flow on the structural plane, and the establishment of the shear model, which can be used f...
