乌东德水电站金坪子滑坡变形监测综合分析

金坪子滑坡距离乌东德水电站坝址不足1 km，在电站前期工程勘察阶段即发现滑坡体存在位移迹象，因此有必要对其展开全面监测和分析。在对滑坡体地形地貌和地质构造详细勘察的基础上，将滑坡体划分为5个变形区，并合理布设了一系列监测设施以分析滑坡体的地表位移、深部位移、裂缝变形等。监测结果表明，金坪子滑坡重点监测区域（Ⅱ区）存在严重蠕滑，滑带明显，其位移变形速率与滑坡所处位置降雨量存在明显的正相关性，且约滞后于降雨1~2个月。

Comprehensive analysis of deformation monitoring of Jinpingzi landslide at Wudongde Hydropower Station

The Jinpingzi landslide is less than 1 kilometer away from the dam site of Wudongde Hydropower Station, and deformation was found during the preliminary exploration stage of the construction, so it is necessary to carry out comprehensive monitoring and analysis. On the basis of detailed investigation of the topography and geomorphology and geological structure of the Jinpingzi landslide, the landslide body was divided into 5 deformation areas, and a series of monitoring facilities were reasonably arranged to analyze the surface displacement, deep displacement and crack deformation. The monitoring results show that a serious creep phenomenon existed in the key monitoring area (DistrictⅡ) of the landslide and the landslide zone was obvious; there was a positive correlation between the landslide displacement deformation rate and the local rainfall, and the landslide generally lagged behind the rainfall for 1～2 months.
