通过在几条公路边坡防护工程中应用香根草的实际经验 ,对在不同条件下所采用的设计规格不同、植物品种配置不同以及施工时间不同 ,所产生的系统功能效果进行分析。同时对公路建设工程中有关边坡处理所涉及的相关工程进行成本与功效对比 ,拟找出一个既经济、又实效的成熟技术方案。 Through the practical experience of vetiver protection applied to several road slope protection projects, the system function effects produced by different design specifications, plant variety configurations and construction times are analyzed under different conditions. At the same time, the relative costs and efficiencies of related works related to slope treatment in highway construction projects are compared, and a mature technical scheme that is both economical and effective is to be found out.
