| 中文摘要: |
| 恰甫其海水利枢纽工程左岸发育一规模较大的F78断层，左坝肩施工开挖时该断层将大范围出露，由此产生施工期和蓄水后左岸山体的稳定性问题，并对工程安全带来威胁。本文采用边坡稳定三维极限(上限)分析方法，对左岸山体在施工期和运行期的三维抗滑稳定性进行分析研究。分析表明，左岸山体施工期和运行期的稳定性较好，但降雨入渗对左岸山体的稳定性影响较大，应考虑适当的排水措施。 |
| 英文摘要: |
| A fault exists in the left abutment of the Qiafuqihai Project, which will lead to the unstable of the slope.The 3-D limit analysis method is applied to estimate the stability of the abutment.The result shows that the left abutment slope is stable in the period of construction,but the storm rainfall will lead to the reduction of safety coefficient.For this reason,the drainage system should be considered in the reinforcement design. |
