Cohesion stress
WebAbstract. The cohesion intercept in the Coulomb shear-strength equation has a significant influence on the location of the slip surface and the factor of safety. The cohesion intercept results from a linear approximation of a segment of a nonlinear shear strength against effective normal stress relationship. Shear strength on a slip surface, at ...
