Formation mechanism and stability evaluation of Mingshui middle school landslide in the Meixi River basin

Mingshui middle school landslide, located on the left bank of the Meixi River, is a typical loose deposits landslide. By analyzing the engineering geological conditions of the landslide, including slope structure, morphological characteristics, and deformation features, the formation of the landslide is considered to experience 4 steps: collapsing and accumulating→sliding→going slowly to stable state→moving again. The landslide deformation is qualitatively analyzed and the landslide stability is determined by the GEO-SLOPE software. The result shows that the slide body of this landslide is currently stable, but the front edge of landslide is close to the limit state in natural conditions, which is very likely to slide or collapse.
