基于毛乌素沙漠公路路基边坡冲刷情况实地调查成果,结合一般路基边坡冲刷理论,分析了与边坡冲刷相关的风沙物理性质、降雨、边坡坡长、坡度、高度、植被以及边坡防护等影响因素,并区别于一般土质边坡论述各因素对风沙冲刷的影响,提出风沙物理性质和降雨是主要的影响因素,而其他因素影响并不明显,建议沙漠公路建设管理中应重视和做好路基排水。 Based on the field survey results of scouring on subgrade slope of Mu Us desert highway and the common scouring theory of subgrade slope, physical properties of wind blown sand, rainfall, slope length, slope, height, vegetation and slope protection Which is different from ordinary soil slope. The physical and property of wind-blown sand and rainfall are the main influencing factors. However, the influence of other factors is not obvious. It is suggested that attention should be paid to the desert-highway construction and management Subgrade drainage.
