Problems solved by technology

[0008] The servo control system currently used in rock uniaxial and triaxial compression full fracture process experiments mainly includes load sensors, actuators and oil sources. The actuators include loading cylinders and loading pistons. The disadvantage is that it is inconvenient to install stress- Water flow-chemical coupling rock uniaxial compression mesomechanics test device, patent application number 200410061081.2, and triaxial compression mesomechanics test device and mesoscopic observation device for the whole process of rock fracture under chemical corrosion, patent application number 200410061080.8, so it cannot be realized Mesomechanical test of stress-water flow-chemical coupling in rock total fracture process

Description

Technical field: [0001] The invention relates to a rock mesomechanics test, and more specifically relates to a stress-water flow-chemical coupling effect and a stress-chemical coupling effect under different confining pressures to a mesomechanics test of the whole process of rock deformation and fracture. It is suitable for rock mechanics tests considering the influence of multiple influencing factors under complex conditions, such as stress, confining pressure, water flow, chemical corrosion, etc. Background technique: [0002] The research on the chemical-water flow-stress coupling process of fractured rocks is one of the most advanced topics in the field of international rock mechanics. It is one of the most basic research topics of many water-related rock engineering, which has very important scientific significance. It is mainly reflected in that, on the one hand, water is the most active factor among many factors affecting the safety of rock engineering. After the ro...
