Abstract

The invention discloses an easily-happening landslide prediction method based on remote sensing technology. The easily-happening landslide prediction method comprises following steps of: obtaining remote sensing images, digital altitude data and geological data; constructing a three-dimensional remote sensing interpretation space scene; detailing interpretation regional landslide distribution characteristics; determining key impacting indicators of landslide growth; and carrying out remote image segmentation processing and establishing an easily-happening landslide prediction model. By use of the easily-happening landslide prediction method, prediction of hidden easily-happening landslides is achieved; the easily-happening landslide prediction method is strong in focusing ability, highly reliable, capable of providing more specific and scientific basis for engineering construction, operation maintenance, disaster prevention and reduction and the like, and capable of increasing the level of engineering operation safety and disaster prevention and reduction.

Description

technical field [0001] The invention relates to the field of engineering geological survey, in particular to a landslide-prone prediction method based on remote sensing technology. Background technique [0002] Landslides are an important type of adverse geological disasters. With the increasing frequency of human activities, the construction of railways, highways, mines, water conservancy, and factory buildings has increased the probability of landslide disasters. Taking the railway industry as an example, the landslide accidents that occurred on the Shanghai-Kunming, Baolan, Yiwan, Lanyu and other railways in recent years have caused great loss of personnel and property. During the construction of some new railway projects, landslide disasters also occur from time to time. Landslide disasters have become a major hidden danger in railway line selection and existing railway operation safety. [0003] At present, survey methods based on remote sensing technology and on-site...
