Experimental study of mechanical properties of highly-stressed rocks under true triaxial unloading conditions with different unloading directions

During the excavation process of deep rock masses, the surrounding rock stress field forms alternating zones of stress increase (loading zones) and stress decrease (unloading zones) near the excavation surface, which can easily trigger instability and failure in high-stress rock masses. Despite nume...
