摘　　要：边坡稳定问题是最常见的工程地质问题之一,影响边坡稳定性的因素也很多,其中路基填料的粘聚力c和内摩擦角φ是影响边坡稳定的主要因素;结合具体算例阐述了φ对边坡稳定的影响比c显著,填筑路基时优先采用φ值较大的材料作为路基填料。Roadside slope stability is one of most common engineering geological issues, there are many factors influencing the slope stability, among which roadbed filler cohesive force c and friction angle φ are the main factors. The concrete examples reveal that the influence of φ on the slope stability is more significant than c and that the roadbed fillers which have larger φ value should be used as materials in roadbed construction.

关 键 词：边坡稳定 粘聚力c 摩擦角φ
