0 INTRODUCTION Landslides are one of the most frequent geological disasters in the world(Wen et al.,2020;Froude and Petley,2018),which have occurred frequently and widely distributed in China for a long *** landslides are essentially a complex multidimensional nonlinear dynamic system affected by its own geological conditions and external factors(Ma et al.,2021;Wang et al.,2019),including geotechnical characteristics,hydrogeology,geomorphologic conditions,climate,and weathering(Ma et al.,2020).The interaction of these factors makes the change of landslide displacement random,fuzzy and variable(Park and Michalowski,2017),and also brings great difficulties to the landslide displacement prediction(Ma et al.,2018).
