基于geo-slope对三峡库区藕塘滑坡的稳定性研究

The reseach on stability of Outang landslide in three gorges reservoir based on geo-slope

水作为影响滑坡最重要的因素之一,一直以来都是滑坡研究的重点。受三峡水库蓄水影响,藕塘滑坡出现变形迹象,局部区域变形较为严重。为研究在蓄水条件下,藕塘滑坡稳定性状况,通过数值模拟方法,采用geo-slope边坡稳定性分析软件计算得出不同库水位条件下滑坡的稳定性系数。结果显示,藕塘滑坡整体稳定性状况较好,随着水位的升高,其稳定性系数呈先减小后增大的趋势,最容易出现破坏的区域位于滑坡前缘。

Water has always been the focus of landslide research,as the most important factor to effect landslide. Affected by the impoundment of the Three Gorges Reservoir, Outang slide show the signs of deformation,especially more severe deformation in some areas. To study Outang landslide stability in the water storage condition,the thesis take the numerical simulation, using geo-slope stability analysis software to calculate the stability coefficient under different water level. The result shows,Outang landslide is in good stability in the whole. As the water level rises ,the stability factor shows a tendency to increase after first decrease ,and the most possible area to slide is located at the front of landslide.
