Pressure -bearing rock failure mechanism of rock unstability process and developments infiltration characteristic test device

The utility model provides a pressure -bearing rock failure mechanism of rock unstability process and developments infiltration characteristic test device, utilize jumbo size pressure -bearing permeability of rock test device, through pressure -bearing rock failure mechanism of rock unstability in -process stress and strain signal, the data acquisition and processing system of acoustic emission signal and apparent resistivity signal, obtain the stress and strain relation of jumbo size pressure -bearing rock failure mechanism of rock unstability in -process, acoustic emission event quantity, position and pressure -bearing water logging are led thoroughly and are risen the rock apparent resistivity change rule who arouses, rock failure mechanism of rock in -process crack is expanded under obtaining water - power coupling, link up with the dynamic evolution law of unstability and corresponding developments infiltration characteristic with it. Research rock water - couple of force closes failure mechanisms and pressure -bearing infiltration characteristic, and the deformation of rock link up and destroys characteristic and the permeability evolution law of pressure -bearing water in - lining up - destructive process is expanded in the crack with strength property, crack extension under water - power coupling. Has important construction value in the aspect of realizing pressure -bearing safe mining under safe water pressure of aquifer on water.
