Slope fission early warning method and system

Abstract

The invention provides a slope fission early warning method and system. According to the invention, early warning is carried out on the slope fission according to the principle that the landslide is separated from the slope body before happening, so that the technical defect that sufficient time cannot be left for personnel and material transfer in the existing image monitoring method is overcome,and the advancement and accuracy of landslide early warning are improved. According to the invention, before fission judgment, the monitoring area is determined based on the InSAR image; a fission monitoring area is delineated; an InSAR image at the (i + 3) th moment is obtained through real-time monitoring; fission monitoring and early warning are carried out on the monitoring points of the delineated fission monitoring area, the monitoring range is reduced, the calculated amount is reduced, fission monitoring is carried out on the basis of an isomorphic curve division mode by utilizing theprinciple that the change trends of the deformation quantities of the fission area are different, and the scientificity and precision of fission monitoring are guaranteed.

Description

technical field [0001] The invention relates to the technical field of risk early warning, in particular to a slope fission early warning method and system. Background technique [0002] Landslide is a geological phenomenon of slope rock and soil sliding along the usual shear failure surface. Landslides often cause huge losses, some even devastating disasters, to industrial and agricultural production and people's lives and properties. Early warning of landslides is the most effective way to reduce landslide losses. However, there are many existing landslide early warning methods. The method based on image monitoring is often unable to detect subtle changes in the slope. The time is very limited, and it is impossible to leave enough time for the transfer of personnel and materials. The method based on probability and statistics has poor accuracy and cannot effectively guide prevention. Contents of the invention [0003] The purpose of the present invention is to provide ...

[0003] The purpose of the present invention is to provide a method and system for early warning of slope fission. According to the principle that the landslide will be separated from the main body of the slope by fission, the fission of the slope can be early-warned, so as to overcome the existing image monitoring method, which cannot give The transfer of personnel and materials leaves sufficient time for technical defects to improve the frontier and accuracy of landslide early warning
