Abstract

The invention belongs to the field of mechanical tests, and provides a device and a method for a low-temperature hydraulic coupling test of a rock-like resin material. The device comprises an environment box body, and the environment box body is filled with a rock-like resin material; a low-temperature refrigeration system used for controlling the temperature in the environment box body to reach apreset test temperature; a high-pressure water injection system used for injecting high-pressure water to carry out a hydraulic coupling test while carrying out vertical pressure loading on the rock-like resin material test piece in the box body of the environment box; a low-temperature deformation measurement system used for measuring the relative displacement of the symmetrical surfaces of therock-like resin material test piece in the box body of the environment box in the hydraulic coupling test process; and a digital monitoring system used for collecting images of the rock-like resin material test piece in the hydraulic coupling test process so as to monitor the hydraulic coupling test process.

Description

technical field [0001] The invention belongs to the field of mechanical tests, in particular to a device and method for low-temperature hydraulic coupling tests of rock-like resin materials. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] The laboratory test technology of rock mechanics is the basis of the theoretical research of rock mechanics and its engineering application. In actual engineering, the mechanical properties of rock will be affected by the function of the project, such as the surrounding rock of the underground cavern of the hydropower station and various hydraulic tunnels. The surrounding rock is affected by the ground stress and the hydraulic erosion should also be considered. There are many primary fissures in the rock in the natural environment. Due to the action of hydraulic force, the expansion of the fissures in th...
