- 摘要:
- 针对某水电工程坝址区地质条件复杂、开挖步序多的实际情况，采用三维有限元法，分析了某水电工程右岸厂房后边坡的稳定性，得到了边坡开挖卸荷、支护中的变形规律和应力分布特性，给出边坡的破坏特征和部位，提出了边坡治理方案。引入强度折减法，以安全系数的形式来分析边坡的稳定性,强度折减法可以与边坡规范相映证，同时该方法采用边坡稳定安全系数，可以直观定性的判断边坡的整体稳定性。工程实践表明，边坡工程稳定性分析结果和加固设计方案合理有效。
- Abstract:
- According to the actual situation of complex geological conditions and more excavation step for a hydropower engineering dam area, the slope stability of back side slope of right bank powerhouse in a hydropower engineering was analyzed by threedimensional finite element. The deformation law and stress distribution characteristic of slope excavation during unloading and supporting were obtained. Failure characteristics and position of slope were given, and the treatment scheme of slope were proposed. The slope stability was analyzed in the form of safety factor by introducing strength reduction method. Strength reduction method can be proved by slope standard, and safety factored of slope stability was used, the global stability of slope can be judged visually and qualitatively. Practical application showed that the analysis results and reinforcement design scheme were reasonable and effective for slope engineering stability.
