攀枝花仁和区啊喇村滑坡特征分析与稳定性评价

Characteristic Analysis and Stability Evaluation of Ala Village,Renhe District,Panzhihua

近年来,滑坡地质灾害在四川西南山区频发,给人民生产生活带来极大影响,威胁人民生命财产安全。在攀枝花市仁和区啊喇村滑坡详细的实地考察基础上,从滑坡基本情况、滑坡形态与变形特征、滑坡物质组成与结构特征、滑坡形成机理及滑坡稳定性等方面探讨该滑坡的发生机理,评价并预判滑坡稳定与不稳定的因素。结果表明,该滑坡目前处于稳定状态,但在极端降雨条件下,局部存在复活可能。在地质灾害防治过程中应重视古滑坡、老滑坡的现状调查与评价,这对防灾减灾具有指导意义。

In recent years,landslides occur frequently in the southwest mountainous area of Sichuan Province,which have a great impact on people's production and life and threaten people's life and property safety.Based on the detailed field investigation of Ala landslide in Renhe District,this paper discusses the occurrence mechanism of the landslide from the aspects of the basic situation of the landslide,the shape and deformation characteristics of the landslide,the material composition and structural characteristics of the landslide,the formation mechanism of the landslide and the stability of the landslide.At the same time,this paper evaluates and predicts the factors of landslide stability and instability.The results show that the old landslide is currently in a stable state,but under extreme rainfall conditions,there is localized resurrection energy,which is of guiding significance for disaster prevention and mitigation.
