Abstract

Considering the condition of mode-I and the mode-II mixed fracture, a concrete damage failure model was established based on the fracture process zone theory. A coupling method of the model and deformable distinct element method was proposed .The progressive failure process of Koyna dam were studied. The reliability and rationality of the proposed method was verified by comparing results of model test and other methods. The results indicate that the initial crack is resulted in tensile stress concentration induced by earthquake. Crack formation causes the redistribution of stress but there are still tension stress concentration phenomenon around the crack tip which resulting in crack expanding. And the crack growth can be divided four phases. After fracture penetration severe dislocation happens between the head and bottom of dam, the kinetic energy decreases but the friction work dramatically increases.

Key words
