A sample preparation mold and sample preparation method for simulating rock mass with multi-layer interlayer dislocation zone

Abstract

The invention discloses a sample preparation mold and a sample preparation method for simulating a rock mass with multi-layer interlayer staggered zones. The sample preparation mold includes an inclination control mechanism for controlling the inclination angle of a sample preparation base and a sample preparation mechanism; The upper surface of the main control cylinder of the mechanism is an inclined surface; the inclination control mechanism is an L-shaped structure including a vertical surface and an inclined horizontal surface; the sample preparation mold provided by the present invention has a simple structure, and can accurately and quickly produce multi-layer interlayer displacement The simulated sample of the rock mass in the belt is beneficial to the experimental research on the strength and deformation behavior of the rock mass in the interlayer dislocation zone, and then obtains accurate and reliable test results. The cylinder is matched for leveling; the sample preparation devices of each layer are prepared separately and then assembled and poured, so that there will be no uneven distribution of test pieces, and the thickness and inclination angle of each layer of samples can be accurately controlled; at the same time, it is avoided to pour layers of the same material for the samples Disadvantages of low density and high density.

Description

technical field [0001] The invention relates to the field of analog sample preparation molds, in particular to a sample preparation mold and a sample preparation method for simulating rock masses with multi-layer interlayer dislocation zones. Background technique [0002] The rock mass with multi-layer interlayer dislocation zone is a special structural rock mass with discontinuous and nonlinear characteristics. The interlayer dislocation zone has a significant impact on the stability of the rock mass. Therefore, it is necessary to The mechanical properties of the rock mass in the moving zone are studied. [0003] Rock mechanics tests mainly include on-site tests and indoor tests, among which in-situ tests have poor economic benefits and are significantly affected by the environment. In recent years, many scholars at home and abroad have studied the mechanical behavior of rock masses containing interlayer dislocation zones, but there are few studies through laboratory tests...

[0003] Rock mechanics tests mainly include on-site tests and indoor tests, among which in-situ tests have poor economic benefits and are significantly affected by the environment

In recent years, many scholars at home and abroad have studied the mechanical behavior of rock masses containing interlayer dislocation zones, but there are few studies through laboratory tests. The reason is that it is difficult to make interlayer dislocation zones during sample preparation. Proto-rock samples, especially those containing interlayer dislocation zones with a certain dip angle

[0004] Researchers usually use rock-like materials for reasonable proportioning to simulate rock samples and study their mechanical properties. Rock-like materials usually include cement mortar materials, resin-based transparent rock materials, rosin oil alcohol-based materials, and gypsum-based materials. materials, etc.; if the inclination angle cannot be controlled when preparing a raw rock sample with an interlayer dislocation zone with a certain inclination angle, it is easy to have the disadvantage that the density of the pouring layer of the same material is low at the top and high at the bottom
