Abstract

The invention discloses a three-dimensional grouting model test device and method. The three-dimensional grouting model test device comprises a first counter-force plate, a second counter-force plate and a third counter-force plate which are sequentially connected in the vertical direction, wherein a confining-pressure counter-force cavity is placed between the first counter-force plate and the second counter-force plate; an axial loading module is placed between the second counter-force plate and the third counter-force plate; a grouted rock mass loading module and a confining-pressure servo loading module are arranged in the confining-pressure counter-force cavity; a sensor connected with a data processing module is arranged in the grouted rock mass loading module. According to the invention, stable loading of the three-dimensional ground stress condition and the groundwater environment in an indoor grouting test is realized, the consistency between the testing conditions and the grouted rock mass initial conditions is effectively guaranteed, and a powerful support is provided for researching the grouting theory.

Description

technical field

[0001] The invention relates to a three-dimensional grouting model test device and a test method capable of applying three-dimensional stress. Background technique

[0002] In the construction of underground projects such as mines and tunnels, problems such as large deformation of surrounding rocks and large amounts of water inflow often occur, and even water and mud inrush disasters may occur, causing huge loss of personnel and property. Grouting, as an effective means of strengthening weak surrounding rock and controlling water damage, has been more and more widely used in underground engineering disaster control. Model test is an important means to study the law of grout diffusion and reinforcement mechanism in the process of grouting treatment. However, there are currently few model test benches for tunnel excavation and grouting, which seriously affects the progress of related research.

[0003] Existing grouting model tests are mostly carried out on s...
