Slope collapse disasters in mountainous area highways severely affect traffic safety. The formation mechanism of these disasters is complex, involving multiple factors such as geological structure, soil and rock properties, hydrogeological conditions, and human activities. This paper explores the formation mechanism of slope collapse disasters in mountainous area highways by analyzing the impact of geological structure, soil and rock properties, hydrogeological conditions, and human activities on slope stability. Meanwhile, it proposes comprehensive control measures, including engineering reinforcement, ecological protection, drainage system design, monitoring and early warning, as well as construction quality control and post-construction maintenance management. Practice has shown that these measures effectively enhance slope stability, reduce the risk of collapse disasters, and ensure the safe and smooth operation of highways in mountainous areas.
