Abstract: This paper presents the dynamic landslide movement trajectory under the action of potential triggering factors. Based on fractal theory, the trajectory of the landslide displacements and its correlations with the precipitations are systematically evaluated. Firstly, the landslide deformation was analyzed with support of the observed sliding monitoring data; Secondly, the fractal dimensions of the deformation curve at each monitoring point of landslide were analyzed by using the boxcounting theorem of fractal dimensions. Lastly, the fractal characteristics of landslide movement trajectory were explored through the variation of fractal dimensions during the study period. The results show that, under the influence of the precipitation, the shear strength of landslide soil decreases and the deformation increases. The deformation trend of fractal dimensions of the landslide movement trajectory increases and the overall trend is increasing.

Key words: Landslide Deformation, Movement Trajectory, Fractal Dimensions
