摘要
黄土地区由于黄土的性质、降雨特征和独特的地形地貌条件,公路边坡溯源侵蚀现象较为普遍。从水源、黄土的性质和地形三方面分析了发生侵蚀的原因。从完善公路排水系统、提高边坡抗侵蚀能力及沟头加固等方面提出了治理措施,并在国道G210陕北洛川塬边坡侵蚀病害治理中应用,取得了良好效果。
The headward erosion on highway slope is a common phenomenon in loess region,because of the nature of loess,rainfall characteristics and the unique terrain conditions.In this paper,the causes of erosion are analyzed from three aspects of water source,the nature of loess and the terrain.Then treatment measures,such as improving drainage system,improving slope anti-corrosion capability and groove head reinforcement,are put forward.These measures were applied in slope treatment in Luochuan Plateau in northern Shanxi along national highway G210,which achieved better results.
