地表大地形监测针对滑坡区地质、地形情况复杂的特点,建立由D级GPS基准点构成的监测网,分阶段逐次加密监测点。为保证点位精度,设立严格的技术要求,并利用滑坡表观现象、定性定量指标、累计位移数学模型结合专家知识等建立滑坡预警预报机制,针对滑坡变形的情况分别采用堆载、喷锚挂网、预应力锚索三种综合应急治理措施,减小了滑坡下滑速率,保证了滑坡的稳定性,为综合治理提供了较好的施工条件。该数据集为1996-2006年长江三峡库区地表大地的形变监测数据。数据格式为csv格式，观测周期为每月观测一次。其中，1996—2001年数据字段分别为：ID（序号），STARTDATE（采集开始时间），ENDDATE（采集结束时间），QUD（区段），POINTNAME（点名），XP（位移后X坐标，单位：米），YP（位移后Y坐标，单位：米），X0（初始X坐标，单位：米），Y0（初始Y坐标，单位：米），X（X方向水平位移变量，单位：毫米），Y（Y方向水平位移变量，单位：毫米），F（水平位移变量，单位：毫米），FX（变形方向，单位：度），H（垂直位移变量，单位：毫米），X1（X方向水平位移月变量，单位：毫米），Y1（Y方向水平位移月变量，单位：毫米），F1（水平位移月变量，单位：毫米），H1（垂直位移月变量，单位：毫米），FX1（变形方向月变量，单位：度），MONSITE（监测点部位）；2002—2006年数据字段分别为：ENDDATE（采集结束时间），STARTDATE（采集开始时间），POINTNAME（点名），QUDUAN（区段），X（X方向水平位移变量，单位：毫米），F（水平位移变量，单位：毫米），Y（Y方向水平位移变量，单位：毫米），DIRECTION（变形方向，单位：度），H（垂直位移变量，单位：毫米），YBLX（X方向水平位移月变量，单位：毫米），YBLF（水平位移月变量，单位：毫米），YBLY（Y方向水平位移月变量，单位：毫米），DIRECTION1（变形方向月变量，单位：度），YBLH（垂直位移月变量，单位：毫米），ID（序号），LOCATION（监测点部位）。

In order to ensure the accuracy of the point position, strict technical requirements are set up, and the landslide early warning and prediction mechanism is established by using the landslide apparent phenomenon, qualitative and quantitative indicators, cumulative displacement mathematical model and expert knowledge. According to the landslide deformation situation, three comprehensive emergency treatment measures are adopted, namely, surcharge load, shotcrete anchor net and prestressed anchor cable, to reduce the sliding rate of landslide and ensure the stability of landslide, It provides better construction conditions for comprehensive treatment.
