This paper took the reservoir landslide as the research object, and analyzed the influencing factors of the stability of reservoir landslides, and determined the influencing factors as the ratio (k/v) of k (i.e., permeability coefficient) to v (i.e., reservoir water-level rise and fall rate) and slope morphological factors (slope shape, slope angle, slope overburden thickness). In this paper, by combining different combinations of the above factors with orthogonal tests and numerical simulation, the characteristics and laws of landslide stability and displacement evolution were studied. The sensitivity ranking of the factors affecting slope stability coefficient and displacement is k/v > slope angle > slope shape > slope overburden thickness and k/v > slope overburden thickness > slope shape> slope angle, respectively. Then, this paper took k/v as the main factor and slope angle, etc. as secondary factors and focused on analyzing the influence law of different reservoir water-level decline changes on the slope stability and displacement evolution.
