Probabilistic Seismic Analysis of the Deep Sliding Stability of a Concrete Gravity Dam-Foundation System

Sensitivity of IDA curves to cohesion: (a) c₁ affects the shearing slide of the starting point on the main sliding surface; (b) c₁ slightly affects the shearing slide of the ending point on the auxiliary sliding surface; (c) little effect of c₂ on the shearing slide of the starting point on the main sliding surface; (d) c₂ is not influential on the shearing slide of the ending point on the auxiliary sliding surface.
