[Departement_IRSTEA]Eaux [ADD1_IRSTEA]Hydrosystèmes et risques naturelsInternational audienceTo assess the shear strength at the rock-concrete contact inside a gravity dam foundation, many theoretical criteria have been developed that consider the joint surface conditions such as roughness and a potential value for the cohesion. In practice, most of guidelines are still suggesting to use the Mohr-Coulomb (M-C) friction criterion that relies on a friction angle and a cohesion values determined from lab tests, literature or engineer experience. For unbounded joints, no true cohesion can be considered since walls are not physically linked. Yet, a value of apparent cohesion, resulting from joint roughness and interlocking conditions is authoriz...
