Based on the rock damage mechanics and the resistivity measurement, the relationship between the electrical and mechanical properties of the rock during the damage process is studied through experiments. The damage variables based on the rock elastic modulus and the resistivity change are established. By quantitative Analyze the changing process of the rock electrical property, invert and analyze the damage state of the rock, build the relationship between the macroscopic mechanical property and electrical property of the rock, establish the rock resistivity test and test method to evaluate the rock damage state.
