are to be solved in the use of traditional methods for gravity dams. One is how to define the limit state function really reflecting the mechanical mechanism of the failure mode; another is how... shear sliding failure [16, 17]. The Mohr-Coulomb criterion is used as the yield function and the plastic potential function for concrete-rock interface sliding. The maximal tensile strength Rt......
