Landslide safety uncertainty evaluation method based on multi-source information fusion

The invention discloses a landslide safety uncertainty evaluation method based on multi-source information fusion, and the method comprises the following steps: constructing a landslide qualitative and quantitative multi-index safety evaluation system, calculating a membership degree corresponding to quantitative index actual measurement time sequence data through a cloud model, and converting the membership degree into a basic probability of an evidence theory; converting an expert comment qualitative index into a basic probability of an evidence theory; for a conflict problem existing in evidence theory fusion, a static weight coefficient is introduced to realize fusion of multiple groups of monitoring data of the same monitoring item, and a dynamic weight coefficient is introduced to realize fusion of different evidences, so that multi-index comprehensive evaluation of landslide safety is realized. According to the method, a landslide safety multi-index evaluation system is constructed, so that the failure
