| 摘 要： | 采用三维弹塑性有限元方法，对金安桥水电站的碾压混凝土重力坝坝基的深浅层抗滑稳定进行了研究。强度储备系数方法计算所得出的渐进破坏过程揭示了重力坝坝基深浅层滑动的模式，同时根据新的重力坝设计规范。对大坝在设计阶段的抗滑稳定安全度进行了分析，大坝坝基的深浅层抗滑稳定是可以保证的。

| Abstract: | 3D elastoplastic FEM Strength Reserve Method adopted to analyze the deep and shallow anti-sliding stability for the dam foundation of Jin'anqiao Hydropower Station is described herein. Computed by the strength reserve coefficient method, the gradual destruction process revealed the mode of the deep and shallow sliding for the dam. And at the same time, the degree of safety for the anti-sliding stability of the dam in the design period is analyzed in accordance with the new design criterion for the gravity dam, which demonstrates that the deep and shallow anti-sliding stability can be ensured. |

| Keywords: | strength reserve coefficient method anti-sliding stability safety factor Jin'anqiao Dam |
