Abstract

This paper details the deformation characteristics of a medium-sized soil landslide in Liangshan Prefecture, Sichuan Province. Through on-site investigation and data analysis, the landslide mechanism is systematically studied: the combined effects of Quaternary loose overburden, artificial slope cutting-induced suspended terrain, and long-term soil soaking by surface water lead to reduced soil shear strength, ultimately forming a traction-type soil landslide. Additionally, two accumulations of unfavorable geological hazards formed by highway construction waste stacking on the slope are prone to inducing debris flow under heavy rainfall. Based on the disaster characteristics and threat scope, two comprehensive treatment schemes are proposed, focusing on diversion of hazard sources and retaining engineering. The research provides technical support for the safe governance of similar landslide disasters in mountainous areas.
