Early identification method of potential landslide based on remote sensing technology

Abstract

The invention discloses an early identification method of potential landslide based on the remote sensing technology, and the method comprises the following steps: S1, obtaining remote sensing data, landform data and geological data of a projection region; S2, extracting a landslide development factor and a value range; S3, building a landslide factor set standard unit; S4, building a model, and dividing a landslide development high-risk region; S5, carrying out the differential interferometer radar remote sensing monitoring of the landslide development high-risk region, extracting the deformation and crack information of the high-risk region, and achieving the early recognition of the potential landslide. The method can achieve the early recognition of the potential landslide in a large range, achieves the focusing of a key region, breaks the point measurement range of a conventional method, achieves the area monitoring recognition, can greatly reduce the manpower and material resource investment, remarkably reduces the early recognition cost of the potential landslide, and improves the project operation safety and disaster prevention and disaster mitigation level.

Description

technical field [0001] The invention relates to the field of engineering geological survey, in particular to a method for early identification of potential landslides based on remote sensing technology. Background technique [0002] Landslide disaster is an important content of engineering geological survey. Conventional ground surveys or remote sensing interpretation methods are used to identify landslides that have already occurred, and it is difficult to achieve early identification of potential landslides. Potential landslides are very harmful to the project and bring great risks to the safety of project construction and operation. Therefore, the early identification of potential landslides is of great significance for engineering construction and operation safety. [0003] Traditional early identification methods of landslides, such as buried sensors and on-site monitoring methods, require a lot of manpower and material resources, and are mostly limited to the scope o...
