In view of the complex geological and topographical conditions of landslide area, a monitoring network composed of d-level GPS datum points is established, and the monitoring points are densified step by step. 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. The data set is the surface deformation monitoring data of the Three Gorges Reservoir area from 1996 to 2006. The data format is CSV format, and the observation period is once a month. Among them, the data fields from 1996 to 2001 are: ID (serial number), StartDate (acquisition start time), enddate (acquisition end time), qud (section), pointname (point name), XP (x coordinate after displacement, unit: m), YP (Y coordinate after displacement, unit: m), x0 (initial X coordinate, unit: m), Y0 (initial y coordinate, unit: m), X (x direction) Horizontal displacement variable, unit: mm), y (horizontal displacement variable in Y direction, unit: mm), f (horizontal displacement variable, unit: mm), FX (deformation direction, unit: degree), H (vertical displacement variable, unit: mm), X1 (monthly variation of horizontal displacement in X direction, unit: mm), Y1 (monthly variable of horizontal displacement in Y direction, unit: mm), F1 (water) Horizontal displacement monthly variable, unit: mm), H1 (vertical displacement monthly variable, unit: mm), FX1 (deformation direction monthly variable, unit: degree), month (monitoring point position); 2002-2006 data fields are: enddate (acquisition end time), StartDate (acquisition start time), pointname (point name), quduan (section), X (horizontal displacement in X direction) Variable, unit: mm), f (horizontal displacement variable, unit: mm), y (horizontal displacement variable, unit: mm), direction (deformation direction, unit: degree), H (vertical displacement variable, unit: mm), yblx (monthly variable of horizontal displacement in X direction, unit: mm), YBLF (horizontal displacement variable, unit: mm), ybly (water in Y direction) Horizontal displacement monthly variable, unit: mm), direction1 (deformation direction monthly variable, unit: degree), yblh (vertical displacement monthly variable, unit: mm), ID (serial number), location (monitoring point position).
