Mechanism and control measures of slope collapse disasters in mountainous area highways
山区公路边坡崩塌灾害形成机理与防治对策

摘要

山区公路边坡崩塌灾害严重影响交通安全，其形成机理复杂，涉及地质构造、岩土体性质、水文地质条件及人类活动等多方面因素。本文通过分析地质构造、岩土体性质、水文地质条件及人类活动对边坡稳定性的影响，探讨了山区公路边坡崩塌灾害的形成机理。同时，提出了综合防治对策，包括工程加固、生态防护、排水系统设计、监测预警及施工质量控制和后期维护管理等措施。实践表明，这些措施有效提高了边坡稳定性，降低了崩塌灾害的发生风险，保障了山区公路的安全畅通。

Abstract

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.
