甘肃环县樊家川乡山体滑坡的发育特征及变形影响因素分析

Development characteristics and deformation influencing factors of landslide in Fanjiachuan village,Huan County,Gansu Province

甘肃省庆阳地区地形以沟谷岸坡为主,黄土层覆盖厚度大,特别是该区北部环县以滑坡为主的地质灾害较为发育。甘肃环县樊家川乡山体滑坡尤为典型,近年来降水量较大,强暴雨等极端天气频发,防灾减灾形势非常严峻,故本文以环县樊家川乡山体滑坡为例,分析其特征以及变形影响因素,以期对陇东黄土地区的山体滑坡类地质灾害防治提供参考。

In Qingyang area of Gansu Province,the landform is mainly gully bank slope,and the Loess cover is thick,especially in the northern part of the area,the landslide is the main geological hazard in Huan County.The mountain landslide in Fanjiachuan Township,Huan County,Gansu Province,is particularly typical.In recent years,the mountain landslide in Fanjiachuan Township,Huan County province has experienced heavy rainfall and frequent extreme weather such as heavy rainstorms,the characteristics and deformation influencing factors are analyzed in order to provide reference for the prevention and control of landslide-like geological disasters in the Loess area of East Gansu.
