| Abstract: | It is believed that the fracture mechacics should be used to research the gravity hollow dam by the analysis and computation of the stress of the dam heel. The effect of the shape,the area and the place of the hollow on the dam heel stress intensity by finite element ways on the basis of the fracture mechanics.The optimum section of the hollow dam is studied and can be an important reference to the design of the gravity hollow dams. |
