Failure Characteristics of Rock Sample during Penetration Tests with the Assistance of Different Free Surface Combinations

AbstractFree surface-assisted TBM disc cutter for rock breaking is an important direction for the optimizing of TBM cutter structure. To study the influence of free surface on TBM excavation, the free surfaces of limited-width opening and unlimited-width opening were presented, and s...
