红谷田水库大石头滑坡稳定分析评价

Analysis and Evaluation on the Stability of Dashitou Landslide of the Honggutian Reservoir

大石头滑坡位于红谷田水库拟选上游近坝右岸,根据滑坡的工程地质条件,采用数值模拟软件GeoStudio对滑坡在不同的工况下进行稳定性计算,并根据计算结果对其稳定性进行分析和评价,提出合理的建议,采用透水性较强的碎块石回填勘探平硐加强地下排水等,以期为工程的后期处理措施提供参考。

The Dashitou landslide is located in the right bank of the proposed site of the Honggutian Reservoir’s upstream.Based on the research of the engineering geological condition of the landslide,this paper makes use of the numerical simulation software to calculate the landslide’s stability under different engineering status,analyzes and evaluates the calculate results and finally puts forward proper suggestion and reference for the post engineering processing.
