冷竹关水电站厂区后边坡稳定性分析

Back Slope Stability Analysis in Powerhouse Area at Lengzuguan Hydropower Station

冷竹关水电站自运行以来未出现因厂区后边坡的变形失稳对工程运行造成严重的影响,但近期有老乡反映,在他们的耕地中出现了裂缝现象。因此,重新对厂区后边坡的稳定性进行评价已成为当务之急。

Since Lengzuguan hydropower station has put into operation,project operation is not strongly impacted by instability due to deformation of back slope in powerhouse area. However,the local people reported that cracks occurred in their farm land. Therefore,it is urgent to make a new stability assessment for back slope in powerhouse area.
