Problems solved by technology

[0005] Mesomechanical tests such as CT real-time scanning test and microscope real-time observation test are an effective means to reveal the internal damage evolution law in the rock fracture process, but CT real-time scanning test and microscope real-time observation test cannot achieve chemical damage under three-dimensional loading conditions. Study on the whole process of corroded rock fracture

Abstract

This invention discloses a chemical erosion rock crack whole process three-axis accurate mechanics test apparatus, which comprises box 2, a pair of load axis 2, water mouth 3, supercharger 4, stainless steel tube 5, and exhaust valve 6. It is characterized by the following: to fix an exhaust valve on the other side of transparent material of box; the exhaust valve is near to the box top as possible; to fix water mouth connected with supercharger through stainless steel tube.

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...
