摘要
岩质边坡稳定性问题在水电工程建设中颇受关注。鉴于单一的某种方法难以客观评判实际问题的稳定性,若将几种方法融合起来,取长补短,对解决工程中的稳定性问题具有实际意义,也是未来发展的一种趋势。本文以官地水电站左岸坝肩下游侧边坡为背景,采用刚体极限平衡法计算该坡体的安全系数和锚索支护数量,然后用有限差分法进行复核,得出了两种稳定分析方法所计算的安全系数和潜在滑裂面的位置。结果表明,两者相差不大。
In this paper rigid block limiting equilibrium method is used to calculate Guandi Hydropower Station left abutment downstream slope factor of safety and number of supporting cables, and fmile difference method is used for check the factors of safety for two kind of stability analyses and potential slide plane positions. The check calculation results indicate that the difference between the two factors of safety is insignificant.
