... of the cleats only affects the net pressure within a specific range in the critical crack. As the cohesion of the cleats decreases, the minimum net pressure required for shear failure decreases significantly, making shear failure more likely. We also introduced a reconstruction coefficient, η, to evaluate...

The simulations, based on lab-scale geometry, verify the experimental observation and frictional cohesion, the key parameter to control pulling force, is quantified. The field-scale simulation indicates a significant reduction...
