摘      要：A calculation formula of thermal-hydro-mechanical(THM)coupling crack initiation rate for brittle rock was derived based on the energy conservation *** self-designed THM coupling fracture test with conductive adhesive electrical measurement method was applied to measuring the THM coupling crack propagation rate of brittle rock *** results show that both calculation and test results of crack initiation rate increased with increase of the temperature and the hydraulic *** are almost in good agreement,which can prove validity of the calculation formula of THM coupling crack initiation rate.
