植被护坡及其在重庆地区的应用

Principles of slope vegetation and application in Chongqing

边坡工程中的植被不仅能美化环境,还具有控制雨水冲蚀、稳定边坡的作用。文章详细论述了植被护坡的边坡滑移面上的边坡稳定系数的评定方法,并与无植被边坡稳定性进行比较,讨论了植被护坡的力学效应和水文作用、植被对雨水冲蚀的控制作用,提出了植被护坡的种植和布置方法的建议。结合重庆地区的边坡特点和气候条件,介绍和分析了该地区的几项典型植被护坡工程及施工方法和施工效果,为植被护坡技术的推广和应用提供借鉴和参考。

Vegetation on slopes not only serves as landscape function, but also controls rain water erosion and slope stability. This paper presents an analysis method evaluating the factor of safety （FOS） of the slope protected by vegetation; Mechanical and hydrological effects of protecting slopes by vegetation are also discussed here. The vegetation function for slope to resist rain water erosion and the methods of planting and designing vegetation are introduced. According to the characteristics of slopes and weather in Chongqing, several vegetated slope engineering projects in Chongqing are introduced here, including designing, construction and effect. It may provides some experience for the practice of slopes vegetation in other areas.
