In view of the Hena landslide occurred in Wuping Township, Zhouqu County, Gansu Province in July 2018, the sliding range, occurrence characteristics and occurrence environment of the landslide were explored by combining multi-source means such as geological data, satellite remote sensing images and field investigation data. Indoor and field tests were carried out to determine the formation characteristics of the landslide area, the rock and soil mechanical properties and characteristics of the sliding zone and the sliding body by means of drilling and well exploration. The results show that: (1) Hena landslide is a progressive landslide with multi-stage, multi-layer and long-distance deformation characteristics. (2) The sliding surface (zone) of landslide is mainly soil sliding zone, which is the dominant factor of current sliding deformation (3) The disaster mechanism of landslide accumulation layer can be summarized as follows: Firstly, due to the influence of frequent earthquakes, the upper and middle deformation of landslide accumulation body produces more cracks, the strength of rock and soil deteriorates, and the slope begins to creep. Secondly, under the action of short-term heavy rainfall, the water-rock interaction makes the cracks further expand, resulting in accelerated softening of internal rock and soil mass, forming a weak interlayer, and aggravating creep deformation. Finally, the slope slides. (4) Hena landslide has the characteristics of obvious stress-seepage-damage interaction, which is a typical post-earthquake rainfall-induced landslide. It can be seen that the resurrection of Hena landslide is a multi-stage landslide with complex deformation characteristics under the action of multiple factors of a specific space-time sequence .
