【Abstract】 Based on rock damage mechanics and resistivity measurements,the relation between the electric property and the mechanical properties of rocks in the process of rock damage was studied by experiments.Damage variable was built,based on the method of testing elastic modulus and the resistivity detection approach.Through quantitatively analysing the change processes of rock electrical,and back analysing the rock damage state,the relationship between the rock macroscopic mechanical and electrical properties was constructed,and the method of rock resistivity testing and rock damage state evaluating was established.更多还原
