Abstract:
Crack propagation criterion was used to analyze the complete crack propagation process in concrete gravity dams. Utilizing the criterion combined with fictitious crack model, the fracture behaviors for a classical concrete gravity dam model were calculated and compared with other numerical methods. The results show that the load versus crack mouth opening displacement curve and crack propagation trajectory in concrete gravity dam model are good agreements with experimental results. When some concrete material parameters, such as initial cracking toughness, fracture energy, tensile strength are given, the complete crack propagation process in concrete gravity dams can be analyzed by using the numerical method.
