The pressure dependent fracture permeability of four granitic rock samples was determined in a triaxial test cell under hydrostatic loading conditions at a temperature of 30°C. Tensile fractures were generated in cylindrical samples by Brazilian tests. Confining pressures were cycled twice between 2 and 50MPa. Permeability and strain responses were determined for two samples with aligned fracture...
Uniaxial and triaxial compression tests as well as splitting tests were conducted on granite specimens after acidic solution erosion at a variety of different pH values and flow rates. The responses of strength loss, deformation behavior and mechanical parameters of the granite were compared and analyzed. The effects of acidic chemical corrosion on microscopic structures, defect morphology and mineral...
