| 摘 要： | 在水电站建设中,由于开挖而形成的一些高边坡,其稳定性状态是影响水电站建设能否顺利进行的关键问题之一.阿海水电站工程地质条件复杂,针对左岸开挖形成的岩质边坡,考虑了不同水位变化、地震、降雨等,对其典型边坡进行稳定性分析研究.采用极限平衡法定量分析了各种工况下的安全程度,同时使用有限元强度折减法进行了应力变形和稳定性分析.在此基础上,提出了对应的边坡治理措施,为阿海水电站的边坡治理提供理论参考. |
| 关 键 词： | 水电站 边坡稳定 极限平衡法 强度折减法 |

| Abstract: | In the construction of hydropower stations, the stability of some high slopes due to excavation is one of the key issues. The geological conditions are very complicated in Ahai hydropower station. The stability of typical rock excavation slopes on the left bank of the station is analyzed with regard to water levels, earthquakes and rainfalls. The safety factors are obtained by the limit equilibrium method in variable conditions. At the same time, the finite element method is used in deformation analysis. The corresponding management measures of slopes are put forward and a theoretical reference is provided for slope treatment in Ahai hydropower station. |
| Keywords: | hydropower station slope stability limit equilibrium method strength reduction |
