| Abstract: | On the basis of evaluations to the failure criteria commonly used and in,,estigations intothe progressive yield process, the failure mechanism, the POssible failure modes of RCC gravitydams by means of elasto-plastic FEM computation, the critical stability criterion and its general evaluating method is proposed. The real working state of the dams designed according to this criterion is discussed. Finally, a comparison between this method and the current standard method is made. |
