Description

Technical field:

[0001] The invention relates to a rock mesomechanics test, in particular to a mesomechanics test of the whole process of deformation and fracture under the coupling action of rock uniaxial compression stress-water flow-chemical coupling. It is suitable for rock mesomechanical loading tests considering the effects of unidirectional compressive stress, 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 rock and soil are eroded by the chemical solution, the physical and mechanical properties of the ro...
