Abstract

The invention discloses a test method for simulating fracture seepage anisotropism under a shear displacement condition. The method comprises the steps of previous preparation, test piece preparation, tapping, test piece loading, normal stress exerting, water injection, shearing, other testing in the same group, experiment data organizing and the like. Fracture test pieces are loaded in a test box internally provided with a shearing box, the test method for simulating the fracture seepage anisotropism under the shear displacement condition is provided, the relation among the shear direction, the water pressure isoparameter and the flow is conveniently studied, and the fracture seepage anisotropic is disclosed at a deeper level.

Description

technical field [0001] The invention belongs to the research field of fissure fluid flow, and in particular relates to a fissure seepage anisotropy simulation test method under shear displacement conditions. Background technique [0002] At present, with the development of society, more and more mineral resources and water resources under complex geological conditions have been explored and developed. Due to the extremely complex geological conditions, the mechanical problems in the mining process are very important for the reasonable selection of mining methods and structural parameters, and the improvement of Mining intensity, rational use of resources, ensuring safe operation of workers and ultimately improving economic benefits are all very important. At present, most of the similar simulation tests are used to simulate the state of minerals more realistically and accurately by using real physical entities on site. However, there is currently no research on the simulati...
