【摘要】 通过分析空腹重力坝坝踵应力的奇异性,提出采用断裂力学理论对空腹重力坝进行研究.用有限元法分析了空腹重力坝的腹孔面积、腹孔位置和腹孔形状对坝踵裂缝尖端应力强度因子的影响,得出了空腹重力坝的最优断面,对空腹重力坝的设计有重要的参考价值和指导意义更多还原

【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.更多还原
