摘　　要：以澜沧江苗尾水电站六兰滑坡为例,分析滑坡的地层、岩土体特征、地质构造、水文地质条件,结合地表监测和钻孔测斜等测量数据,着重分析滑坡的形成机制,预测滑坡未来的发展趋势,并给出合适的防治建议。因六兰滑坡为典型的因库区蓄水诱发产生的古滑坡,理清其古滑坡复活机理对库区同类地质条件的滑坡防治、监测具有一定的指导意义。Taking the Liulan landslide of Miaowei hydropower station of Lancang river as an example,this paper analyzes the stratigraphic,geotechnical characteristics,geological structure and hydrogeological conditions of the landslide.Combined with the surface monitoring and borehole survey data,this paper analyzes the formation mechanism of the landslide,predicts the development tendency of the landslide in the future,and gives appropriate suggestions for prevention and control.Because the Liulan landslide is a typical ancient landslide induced by impoundment in the reservoir area,clarifying the mechanism of its ancient landslide resurrection is of certain guiding significance to the landslide prevention and control and monitoring of similar geological conditions in the reservoir area.
