| 摘 要： | 采用三维有限元方法,用强度储备系数,对江坪河双曲拱坝坝肩抗滑稳定性进行分析.计算结果表明,原加固方案有一定效果,但左岸坝肩不满足抗滑稳定要求,对断层进一步加固后,坝基的整体强度储备系数达到3.6,坝肩稳定安全度基本满足要求.

| Abstract: | The sliding stability of the abutments of Jiangpinghe double-curved arch dam is analyzed by 3-D nonlinear FEM with strength safety coefficient.The result shows that the first hand strengthening scheme has a certain amount of active effect for the right bank abutment but the sliding stability of the left bank abutment doesn't meet the stipulation of design specification. After the faults across the abutments are strengthened,the integral strength safety factor of the dam foundation reaches(3.6),that is in the stipulated safety limits. |
