Abstract

This paper takes a tailings accumulation slope as a case study and systematically explores the structural characteristics of plant roots and their impact on slope stability by combining fractal theory with numerical simulation. The box-counting dimension was introduced to quantify the spatial complexity of root systems, and the fractal characteristics of two typical plant roots, Pittosporum tobira and Vetiveria zizanioides, were analyzed. Slope stability simulations under multiple conditions (no rainfall, light rainfall, heavy rainfall) were conducted using Midas GTS NX. The results indicate that a higher root fractal dimension corresponds to greater shear strength of the root-soil composite. Vegetation can slightly increase the safety factor, but its controlling effect on deep-seated landslides is extremely limited. ’ primarily suppress surface erosion, while woody roots provide deep anchoring and shear support. Roots within the slope experience both tension and compression. The state of stress (tension or compression) is related not only to the root’s position on the slope but also to its growth direction, even for roots at the same location.
