地下水浮托力对近水平岩层滑坡形成的促进作用——以三慧寺滑坡为例

The Promotion of Groundwater Uplift Force on the Formation of Near-Horizontal Rock Mass Landslide

2020年7~8月,仁寿县普降大暴雨,始建镇三慧寺发生顺层缓倾的基岩滑坡,基于调查访问和现场勘探,本文对滑坡的变形过程、形成机理进行了分析。通过本次研究表明:斜坡岩土结构及地形地貌为滑坡提供了基础条件,地下水浮托力为滑坡的形成提供了促进作用;滑体在浮托力作用下沿层面发生推移式滑动的过程,该类型滑坡在红层、丘陵地区常有发生,本文以三慧寺滑坡为例研究讨论地下水浮托力对近水平岩层滑坡的促进作用,研究成果对其他类似滑坡失稳机理研究具有借鉴意义。

Heavy rainfall in Renshou,Sichuan in July-August 2020 triggered gently inclined bedrock bedding landslide in Sanhui Temple,Shijian Town.This paper has a discussion on deformation process and genetic mechanism of the Sanhui Temple landslide.The study indicates that the rock and soil structure and landform of the slope provide the basic conditions for the landslide and groundwater uplift force promotes the formation of the landslide.
