Abstract
In order to determine the change law of permeability of rock mass under different pressure a series of both borehole routine water pressure tests and high pressure water pressure tests were conducted for the rock masses in the high pressure bifurcation area of the Qiaongzhong pumped -storage power plant .The difference in the test results between the routine water pressure test and the high pressure water pressure test was deeply discussed by comparison and analysis of the test results .The study results show that the permeability coefficient of the fissured rock mass under high pressure is far exceeds that under conventional pressure .What’s more, the borehole acoustic sounding video recording data analysis reveals that the change law of permeability of rock mass is closely related to distribution of fissures of rock mass , to connection and opening of the fissures .关键词
