Problems solved by technology

However, this overall heating model method has many disadvantages: 1. During the long-term operation of the project, the strength of the broken zone and weak layer gradually decreases, and the mechanical parameters of other rock masses do not change much. The overall heating model makes the rock The mechanical parameters of the body also change, which does not conform to the actual working conditions of the project. 2. The rock mass is formed in the form of blocks, and the material difference between the rock mass and the weak layer is

Description

technical field [0001] The invention relates to the technical field of geomechanical model test materials and preparation, in particular to geological temperature-sensitive materials capable of simulating weak layers, a manufacturing method thereof, and a temperature control system. Background technique [0002] The geomechanics model is to study the influence of geological structure conditions on engineering from the point of view of mechanics and by means of experiments. Weak layer refers to the structural surface whose mechanical strength is obviously lower than that of the surrounding rock, and is generally filled with a certain thickness of weak material. Such as muddying, softening, broken thin interlayer, etc., have the characteristics of low strength, high compressibility, and easy softening when exposed to water. The weak surface is a controlling weak surface in the geomechanics model test, which can affect the structure of the rock mass and control the stability o...
