%X A new thermo-gaseous-mechanical coupling laboratory apparatus measuring rock properties is developed and used to measure gas flow rate for two different specimen sizes of 50 mm and 100 mm in diameter. Either axial or radial permeability way can investigate gas transport properties in rocks. The maximum test temperature is 90 ℃,the maximum axial force of triaxial piston can be 1 000 kN and the maximum confining pressure is 40 MPa. Difficult techniques for permeability test of low permeability medium such as long testing time(lasting one week),sample sealing performance under high temperature(less than 90 ℃),accuracy of micro-flow measuring,uniformity and constancy of testing temperature during test are solved. Tests are carried out on dense marble samples taken from Jinping II hydropower station. Test results show that the apparatus can satisfy the requirement for thermo-gaseous-mechanical coupling test for low permeability medium. Using this equipment,transport parameters of surrounding rock are available for environment evaluation and steady analysis in important projects such as oil/gas storage in depth,oil/gas exploitation in low permeability oil/gas field,gas drainage in gas mine and geological disposal of high radioactive waste.
