摘　　要：澜沧江左岸沿江公路表村至营盘段是黄登、大华桥及上游各电站建设的“生命线”及沿线的唯一通道。大华桥水电站蓄水造成地质灾害频发,K147+000~K147+125段古滑坡体范围内滑坡发生滑动,影响了公路的正常运行,通过现场调查,对滑坡稳定性分析,探讨滑坡变形特征及形成机制,并考虑公路路基安全、库岸稳定,为沿江公路滑坡治理提供科学依据,为同类公路病害治理提供参考。The section from Biaocun to Yingpan of the highway along the left bank of the Lancang River is the"lifeline"for the construction of Huangdeng,Dahuaqiao,and upstream power stations,as well as the only channel along the line.The storage of Dahuaqiao Hydropower Station has caused frequent geological disasters,and the sliding of landslide within the range of ancient landslide mass in section K147+000~K147+125,affecting the normal passage of the highway.Through on-site investigation,we analyzed the stability of the landslide,considered the safety of the highway roadbed and the stability of the reservoir bank,and discussed the deformation characteristics and formation mechanism of the landslide.The research results provide a scientific basis for landslide treatment of highways along the river and a reference for the treatment of similar highway diseases.
