某特大型滑坡稳定性及敏感因素分析

Analysis on Atability and Sensitive Factors of a Huge Landslide

本研究以某特大型滑坡作为研究对象,通过现场勘察、区域分析及位移变形监测研究了该滑坡的稳定性,分析了其变形破坏特征及机理,计算的稳定性系数在0.96~3.01,滑坡局部处于不稳定状态,特别是在暴雨工况下。进一步对滑坡稳定敏感因素进行分析,结果表明,滑坡处于非稳定状态时,内摩擦角对滑坡稳定性影响最为显著。本研究结果可为该滑坡和类似滑坡的治理提供建议。

In this study, the stability of a particularly large landslide is studied on the basis of field investigation, regional analysis and displacement and deformation monitoring. The characteristics and mechanism are analyzed and the stability coefficient is between 0.96 and 3.01. Part of the landslide is in an unstable state, especially under rainstorm conditions. Furthermore, the landslide stability sensitive factors are analyzed, and the results show that the internal friction Angle affects the landslide stability most significantly. The results of this paper can advise on the treatment of this landslide and the similar landslides.
