摘要
结合锦屏一级水电站进水口高边坡的稳定性研究,进一步总结了高山峡谷地区水电高边坡的研究方法。在现场地质条件调查的基础上对工程高边坡的破坏模式进行判断,以采取相应的计算分析方法。高山峡谷地区边坡稳定性受地貌的影响明显,因此稳定性分析模型必须真实反映研究区的地形地貌特征,建立精确的计算模型。计算分析中采用多种方法相互印证,相互补充。经过多种手段的计算研究,结果表明,锦屏一级水电站进水口边坡整体稳定,但在边坡上部的2(6)层中需采取一定的支护措施。由此不仅可以保证锦屏一级水电站的工程安全,且为高山峡谷地区类似的水电工程高边坡的稳定性研究提供了可借鉴的经验和方法。
During the construction of hydropower station, high cutting rock slopes are inevitably encountered, especially in the areas full of huge mountains and gorges. To some extent, the research on the stability of rock mass and the high cutting slopes in the areas of hydropower station is more important than that of the dam itself. According to the research on the stability of intake slopes of Jingpin Hydropower Station, which is located on Yalongjinag River, the study methods of huge mountains and gorges are systematically summarized. First, a field investigation on geological condition and the rational parameters of rock mass is taken. Then, the possible failure style of the slopes is estimated. Because the terrain has great influence on the stability of the slopes in this area, a precise model, which can reflect the topography vividly, is established to analyze the stability of the slopes. During the process of the analysis, many methods are used to verify the results. The following conclusions can be drawn： the general stability of the intake slope of Jingpin Hydropower Station is acceptable, while some measures should be taken to reinforce the slopes in the upper layer of T2-3z^2（6）. The research, not only ensures the safety of Jingpin Hydropower Station, but also provides some helpful experience to the stability research on high cutting slopes of similar projects.
