狮子包滑坡是三峡库岸上一个典型的顺层滑坡。在2001年该滑坡沿表层滑动面下滑。如今三峡水位不断上涨,地下水对滑坡稳定产生不利影响。此外,可能的水库诱发地震也给狮子包滑坡带来了安全隐患。本文在深入分析滑坡地质特征、结构特征和变形特征的基础上,对滑坡的成因机制和影响因素进行了深入研究,并用极限平衡法进行不同条件下的稳定性计算与评价,最后提出参数设计建议、两套防治方案。
The Lion Bao landslide is a typical bedding landslide on the bank of the Three Gorges Reservoir. In 2001 the slide slid along the surface slip. Now that the water level in the Three Gorges is on the rise, groundwater adversely affects the stability of the landslide. In addition, possible reservoir-induced earthquakes also pose a safety risk to the Lion’s pack landslide. Based on the in-depth analysis of landslide geological features, structural features and deformation features, this paper deeply studies on the formation mechanism and influencing factors of landslides, and calculates and evaluates the stability under different conditions by using the limit equilibrium method. Finally, Two sets of control programs.
