Failure Criteria of Gas-Infiltrated Sandy Shale Based on the Effective Stress Principle
Pore gas has a significant influence on rock strength. This study performed triaxial compression tests of gas-infiltrated sandy shale samples to investigate the strength characteristics under gas pressures of 0 and 2 MPa. The effective stress coefficient was evaluated while considering the gas and s...
