acoustic emission (AE) locations were obtained by adopting an AE monitoring system. Based on spatial AE distribution evolution of red sandstone during multi-stage triaxial deformation, the relation between spatial AE events and triaxial deformation of red sandstone was analyzed. The results show that before peak strength, the spatial AE events are not active and distribute stochastically in the specimen......
