Abstract
A reservoir bank landslide susceptibility evaluation method. The method includes the following steps: S1, acquiring geophysical parameters; S2, calculating stability of a reservoir bank after impoundment through a static geological evaluation model according to the geophysical parameters; S3, obtaining an average displacement velocity in a geographic coordinate system according to single look complex (SLC) images after impoundment; and S4, according to the average displacement velocity in the geographic coordinate system and the stability of the reservoir bank after impoundment of the reservoir, obtaining a reservoir bank landslide susceptibility grade. According to the method, a problem that present landslide susceptibility evaluation methods all adopt a single model to evaluate landslide susceptibility, which has low evaluation accuracy of the landslide susceptibility is solved.
