摘　　要：澜沧江梯级电站陆续建成并蓄水,库岸古滑坡复活将成为一种常态化,是水库坍岸的一个主要类型。以六兰路口滑坡实际工程为例,结合滑坡规模和特点,理清巨型滑坡勘察工作思路,通过无人机三维影像技术、工程地质调绘、钻探勘察及建立滑坡区变形监测网等方法,分析与研究库区古滑坡的成因、形成机制、发展趋势等,从而掌握滑坡变形特征,得出准确的勘察结论。实践证明,对水库库区古滑坡勘察工作方法是切实可行的,对滑坡前期工作和后期分析论证具有普遍性的指导意义,可为类似滑坡勘察工作提供参考。It is a main type of reservoir bank caving that the reactivation of ancient landslide in reservoir bank becomes habitus along with the building up and retaining water of cascade hydropower station in Lancang River. This article takes a practical engineering-Liulan Crossroad Landslide as an example, combines with the scale and characteristic of the landslide, makes the working thought in investigation of giant landslide clear, researches and analyses the origin, development mechanism and tendency of ancient landslide in reservoir region, by means of UAV（Unmanned Aerial Vehicle） 3 d imaging technology, engineering geological mapping, drilling, establishing the deformation-monitoring network in the landslide area and so on, in order to master the landslide deformable features and draw a correct reconnaissance conclusion. Practice has proven that the investigation working method on ancient landslide in reservoir region is practicable. This article has universal guiding significance to preliminary work and latter analytic demonstration of landslide, it also a provides reference for the similar landslide investigation work.
