Shear Behavior of Soft Rock Exposed to Alternate Dry and Wet under Constant Stress

The surface of cutting rock slope has exposed to alternate dry and wet conditions for a long time, and they are weathered. We developed direct shear testing apparatus that can expose soft rock specimen to alternate dry and wet conditions under constant shear and normal stress, and are investigated about relationship between deformation properties and the shear behavior of soft rock under dry and wet conditions
