Embodiment 1

[0061] In a specific embodiment, the technical solution of the present invention can be realized by the following methods:

[0062] (1) Slope original terrain input

[0063] First input the original topography of the slope, input the topographic contour (contour point) of the slope into the program, and then select the appropriate calculation parameters according to the size of the slope and the accuracy of the contour line (contour point), and use Kerry Golden interpolation converts contour lines (contour points) into DEM (digital elevation model), and uses the original terrain as the basis for later calculation of slope deformation.

[0064] (2) Monitoring point position input

[0065] Input the three-dimensional coordinates of each monitoring point, and its value can be relative coordinates or absolute coordinates, but it should be consistent with the coordinate system of the original terrain of the slope. Because in the later calculation process, the calculation of slope...

technical field [0001] The invention relates to the fields of disaster prevention and reduction in geotechnical engineering, deformation body monitoring, and landslide risk analysis, and in particular to a method and system for calculating slope space deformation and failure trend based on tilt and vibration monitoring data of a sliding slope body. Background technique [0002] As a common geological disaster, landslides will bring certain harm to people's production and life. Monitoring the deformation of slopes is an important measure to reduce the losses caused by landslides. At this stage, the monitoring of slope deformation is changing from traditional manual monitoring to automatic monitoring. How to quickly and accurately monitor slope deformation and how to know the safety status of slope through monitoring data in a timely manner is the key to reducing landslides. Disaster problems that need to be solved urgently. [0003] At present, the main technologies adopted ...
