黄土路堑边坡冲蚀破坏各指标间的相关关系

Corresponding Relationship Among the Indexes of Highway Cut Slopes Erosion in Loess Area

甘肃黄土地区公路路堑边坡受水冲蚀破坏现象十分严重。影响边坡冲蚀破坏的因素很多,如坡顶汇水、坡长、坡度、植被覆盖度、边坡土干密度、粘粒含量、综合抗剪力等。本文通过大量野外调查资料总结了黄土路堑边坡冲蚀的一般规律和边坡冲蚀破坏各指标间的相关关系,并提出了防治路堑边坡冲蚀破坏的若干建议。

The highway cut slopes in the loess area in Gansu province are seriously eroded by waterThere are many effect factors which greatly influence the cut slopes erosion such as the catchment area on the top of the cut slopes,the length of the slopes,the angle of the slopes,vegetation covering,drysoil density,clay content,and the comprehensive shearing resistance etcBased on many field survey data this paper not only concludes the general pattern of the highway cut slopes erosion in loess area and the corresponding relationship among the respective indexes of the highway cut slopes erosion but also gives some advices to prevent it
