公路边坡植被防护技术的发展研究

在今后的数十年里,在复杂地形条件下修建公路的情况会越来越多,高填深挖、开山通路是难以避免的;同时工程建设所面对的气候、地质状况也更加复杂,工程建设对环境的影响越来越大,而环境的反作用也越来越明显。工程建设破坏沿线生态系统、植物覆盖层消失、边坡裸露在大气环境中,不仅可引起水土流失,还能引发滑坡、泥石流等地质灾害,危及行车安全。采用植被固坡可以弥补传统工程措施的不足,在实现固土护坡的同时,还能恢复生态环境。本文针对公路边坡的植被防护技术展开研究,介绍植被防护技术理念、技术的发展,提出植被防护的基本原则,并结合工程提出边坡植被防护设计具体方案。

Research on the Development of Highway Slope Vegetation Protection Technology

In the coming decades,more and more roads will be built under complex terrain conditions,and it is inevitable to dig and excavate high fill and mountain passes.At the same time,the climate and geological conditions faced by the project construction are more complex,and there will be more and more special areas such as deserts,loess,frozen soil and expansive soil.The destruction of the ecological system,the disappearance of plant cover layer and the exposed slope in the atmospheric environment along the route of project construction not only causes soil erosion,but also causes geological disasters such as landslides and mudslides,which threaten the safety of vehicles.The adoption of vegetation slope fixation can make up for the deficiency of traditional engineering measures.This paper studies the vegetation protection technology of highway slope,introduces the concept and development of vegetation protection technology,puts forward the basic principles of vegetation protection,and proposes a typical section vegetation protection design scheme based on engineering.
