The stress and stability analysis of arch dam and abutment are the main task of traditional arch dam design. Nowadays there are two kinds of analysis method to use. One method is the arch-cantilever load-distribution method, in which the arch dam stress and abutment thrust are calculated, while the stability of abutment is evaluated by rigid body method or other method. The other is FEM method, which evaluates the arch dam stress and stability of abutment at the same time.
