路侧弃土是山区高速公路建设中较为常见的弃土方式，由此引起的路基变形破坏时有发生，但相关的研究却少见。采用数值分析方法，就路侧弃土对路基稳定性的影响进行分析。结果表明：弃土于路基下侧，对路基稳定和变形的影响较弃土于路基上侧小；水对弃渣体及路基的稳定性有较大影响，弃土于路基上侧时路基稳定系数可降低约18%，弃土于路基下侧时弃渣体的稳定系数可降低约10%；工程上应加强路侧弃土外部与内部防排水设施的设置，以减少水的影响。

Roadside spoil is one of common modes of spoil in construction of expressways in mountainous area and often causes deformation and failure of roadbed, but the relevant studies are rare. This paper analyzes the influences of roadside spoil on roadbed stability by means of numerical analysis method. The result of analysis shows that the spoil under the roadbed has less influences on roadbed stability and deformation than that above the roadbed; water remarkably affects waste slag and roadbed stability, the roadbed stability coefficient can decrease by approximate 18% when spoil is above the roadbed, and the stability coefficient of waste slag can reduce by approximate 10% when spoil is under the roadbed; in engineering setup of water resistant and drainage facilities outside and inside the roadside spoil should be strengthened to reduce influences of water.
