Problems solved by technology

[0025] In order to overcome the inability to make a rock mass sample model with complex three-dimensional fractures in the existing sample preparation methods of fractured rock mass models, the size and direction of the cracks cannot be controlled, the filling and non-filling of the cracks cannot be considered at the same time, and the repeated requirements cannot be met. Due to the requirements of sample preparation and poor practicability, the present invention provides a sample preparation mold for a fractured rock mass model sample, which can conveniently and quickly produce a rock mass sample model containing complex three-dimensional fractures, and strictly control the size of the fractured rock mass. The size and direction can simultaneously consider whether the cracks are filled or not, which can meet the requirements of repeated sample preparation, and can be combined and assembled according to the different sample sizes to improve the practicability of the sample preparation mold

Abstract

The invention relates to a sample preparation mold for a fractured rock mass model sample. The sample preparation mold comprises a base and an outer frame structure, wherein an inner cavity of the outer frame structure is used for forming the fractured rock mass model sample, and the outer frame structure is positioned on the base. The sample preparation mold further comprises a plug board and a fracture position regulating structure, wherein the plug board is made of a fusible alloy material, the fusible alloy material is formed in a solid state at the normal temperature and can melt after being heated to a melting point temperature; the fracture position regulating structure is positioned in the outer frame structure and is connected with the plug board. The sample preparation mold provided by the invention can conveniently and quickly make the rock mass model sample with a complicated three-dimensional fracture, strictly control the size and the direction of the fracture, simultaneously consider the situation whether the fracture is filled or not filled or not, satisfy the requirements for repeated sample preparation and be combined and assembled according to different sample sizes, so that the practicability of the sample preparation mold is improved.

Description

technical field [0001] The invention relates to a rock mass sample mold for making a complex three-dimensional fracture network. In particular, the invention can combine the sample preparation molds in various combinations according to test requirements, so as to realize the production of rock mass models of different scales. The invention belongs to the technical field of engineering. Background technique [0002] The important difference between rock and rock mass is that the rock mass contains fissure surfaces, which destroy the integrity and continuity of the rock itself, and the strength of the rock mass is much lower than that of the rock mass. Because the rock mass is the product of geological history, and has been reshaped by the later crustal movement and the external force of the earth, it has a certain rock composition and fracture network. Therefore, the rock mass is not homogeneous, but heterogeneous and various. Anisotropic and discontinuous composite structur...
