Effect of Confining Pressure on the Damage Evolution and Failure Behaviors of Intact Sandstone Samples During Cyclic Disturbance

Under cyclic disturbances, the free faces of the surrounding rock that simultaneously bears a high geostress may pose potential engineering hazards related to large deformation or displacement. However, the mechanism for the damage and failure of the rock under coupling conditions of triaxial stresses and cyclic disturbance remains elusive. The primary objective of this study was to investigate the effect of confining pressure on the damage...
