The increase in the joint shear strength restricts the slip failure along the joints and enhances the resistance of the rock mass to cutter-induced penetration, unfavorable to TBM excavation. (2) As the joint shear strength increases, the primary and secondary cracks change from the mixed shear-tensile to tensile mode at the initial stage.
