STUDY ON THE DYNAMIC FRACTURE PROCESS AND FRACTURE LAW OF CRACKS ROCK UNDER THE COUPLED MECHANICAL-HYDRAULIC-CHEMICAL ENVIRONMENT
Research on the fracture characteristics of cracks rock under the coupled mechanical-hydraulic-chemical (MHC) environment is the basic issue in nuclear waste treatment,storage and exploitation of fossil energy resources,earthquake mechanism and estimation of long-term stability of rock and soil structures.The microfracturing process test of multi-cracks rock specimen under uniaxial compression with the coupled MHC environment is conducted by using a meso-mechanical testing system.The dynamic fracture characteristics of cracks under the coupled MHC environment are obtained.The coalescence modes of cracks are discussed.The laws of chemical corrosion on rock strength under different chemical solutions are presented for limestone specimens with preexisting cracks.
