Abstract
In this study, uniaxial and triaxial compression acoustic emission (AE) tests were implemented to investigate the AE effect and failure characteristics of sandstone under different confining pressures (σ3). The evolution of AE parameters in the rock failure process and fracture fractal dimension characteristics after failure were analyzed. The results revealed that the activity of the AE signal is strongly related to σ3. The evolution of the Ib...
