Problems solved by technology

[0004] At present, the indoor rock mass fissure seepage test generally uses plexiglass to simulate the crack wall, or splits the sampled core to obtain a random crack surface. Therefore, there is a large gap between the experimental simulation results and the actual seepage characteristics

Abstract

The invention discloses a rock coarse fracture seepage simulation model and a making method. The rock coarse fracture seepage simulation model comprises a fracture main board, a left mounting board, a right mounting board, an upper mounting board and a lower mounting board, the fracture main board is of a cuboid structure, a hydrophobic area is arranged on one side of the cuboid structure, a water gathering area is arranged on the other opposite side, the hydrophobic area is communicated with the water gathering area, the outer side of the hydrophobic area is matched with the left mounting board, and the outer side of the water gathering area is matched with the right mounting board; the upper surface and the lower surface of the cuboid structure are respectively matched with the upper mounting board and the lower mounting board, and a pressure measuring hole communicated with a communicating area between the hydrophobic area and the water gathering area is formed in the upper mounting board. 3D printing technology is adopted to manufacture the fracture main board which is fixed through the upper, lower, left and right mounting boards, and a bolt or a water pressure sensor is mounted on each mounting board, so that the making method of the rock coarse fracture seepage simulation model is simple to make, convenient to experiment and capable of reflecting rock fracture seepage characteristics more really and more accurately.

Description

technical field [0001] The invention relates to a method for making a fissure simulation model, in particular to a rough fissure seepage simulation model of a rock mass and a method for making it. Background technique [0002] In recent years, with the construction of a series of large-scale water conservancy and hydropower projects, mining and petroleum projects, nuclear waste storage, and large-scale underground water-sealed cavern oil depots, the study of rock mass seepage characteristics has attracted widespread attention. In natural rock mass, a structure composed of stone blocks and macro-cracks or joints that divide the blocks, the micro-cracks and macro-cracks of the blocks provide storage places and migration channels for groundwater and oil and gas. Most of the disasters such as hydropower project dam failures, slope instability, mine excavation subsidence, and tunnel water and mud inrush are mostly related to rock formation water infiltration. Therefore, it is of...
