公路路基边坡失稳及防治措施研究

Study on Instability and Prevention Measures of Highway Subgrade Slope

公路路基边坡失稳会造成路基破坏,出现滑坡、崩塌、剥落、断裂等现象,影响公路的正常使用,也给行车带来了极大的安全隐患。文章从地质因素与非地质因素两个方面,分析了影响路基边坡失稳的主要因素,阐述了公路路基失稳的主要防治措施,并结合工程案例,介绍了挖台阶法的具体施工应用与效果。

Unstable slope of highway subgrade will cause subgrade damages such as landslide,collapse,exfoliation,or fracture,affecting the normal use of highways,and also bringing huge safety risks to traffic. From the aspects of geological and non-geological factors,this article analyzed the main factors affecting the slope instability of the subgrade,described the main prevention and control measures for the instability of highway subgrade,then combining the engineering cases,it introduced the specific construction application and effect of step excavation method.
