Description

Technical field:

[0001] The invention relates to a mesomechanical test of the whole process of rock deformation and fracture, and more particularly relates to a mesomechanical test of the whole process of rock fracture under chemical corrosion under three-dimensional compression. It is suitable for the mesomechanical loading test of the whole process of rock deformation and fracture considering the influence of confining pressure and chemical solution. Background technique:

[0002] The study of rock strength and fracture characteristics under chemical corrosion is one of the most basic topics in nuclear waste treatment, geothermal development, oil drilling, earthquake mechanism, storage of toxic and harmful substances, and long-term stability evaluation of geotechnical engineering. One of the most cutting-edge topics in mechanics research. The main reason is: groundwater is everywhere. The chemical reaction and stress corrosion of corrosive substances in the environment r...
