针对我国高速公路边坡水土流失防护存在形式多样、效果不一的问题 ,以洛界高速公路为例 ,介绍了边坡水土流失植物防护的设计方案 ,在采用人工模拟该区间百年一遇暴雨和径流试验对方案可行性验证的基础上 ,进行了效益分析 ,经过讨论认为该方案可供河南省及周边地区其它高速公路边坡采用植物防护时借鉴和参考 ,高速公路边坡应大力提倡采用植物进行防护 ,为保证施工质量应推行招投标制和监理制等。 Aiming at the problems of various forms and inefficiencies of soil and water loss prevention of highway slopes in our country, this paper introduces the design scheme of plant protection of soil and water loss on slope by taking Loojie Expressway as an example. Runoff test on the basis of the feasibility of the program, conducted a benefit analysis, after discussion that the program for other highway slopes in Henan Province and its surrounding areas to use plant protection reference and reference, the highway slope should vigorously promote the use of plants To carry out protection, to ensure the quality of construction should be implemented bidding system and supervision system.
