摘要：
The hydromechanical behavior of deep intact Beishan granite is investigated with MTS815 rock mechanics test system. With the help of 3D acoustic monitoring system, a special attention is paid on the damage evolution process and its impact on the permeability of rock sample during triaxial compression test. The experimental results indicated that the damage evolution has a significant influence on the permeability variation of granite. Under the same confining pressure, a good accordance between the damage and permeability evolution tendency is noticed, which can be divided into three phases.
