摘　　要：以湖南省永州市冷水滩区皮肤病防治所岭口麻疯村滑坡为研究对象,通过工程勘查,对滑坡的工程地质条件进行了评价,通过室内试验、参数反算、工程经验类比方法综合确定滑带土的抗剪强度指标,采用传递系数法,分别对滑坡在天然、暴雨两种工况下进行了稳定性计算及评价,结合该滑坡类型、变形特征、危害对象,确定采用整坡工程+挡土墙工程+截排水沟工程+锚喷工程+监测工程的综合治理方案,经过工程治理后,提高了边坡稳定性,并消除了滑坡隐患。该稳定性分析方法及工程治理技术可为类似堆积型浅层滑坡工程治理提供参考。In Hunan province,which supply opening Lengshuitan skin diseases prevention leprosy village landslide as the research object,through the engineering exploration,engineering geological conditions of landslide is evaluated,through the indoor test,the inversion analysis experience,engineering analogy method determining the shear strength of slip zone soil index,using transfer coefficient method,respectively,of landslide in natural,storm two kinds of working conditions for the stability calculation and evaluation,combined with the deformation of the landslide types,characteristics,harm object,determine the whole slope retaining engineering in engineering++intercepting drainage engineering combined bolting and shotcrete++and the comprehensive monitoring plan,after project governance,improve the slope stability,And eliminated the landslide hidden danger.The stability analysis method and engineering treatment technology can provide a reference for similar accumulation type shallow landslide engineering treatment.
