通过 1999年科技立项和在上分线二级路改造工程中运用香根草等高植物篱护坡试验示范的基础上 ,2 0 0 0年、 2 0 0 1年在江西兴国公路段、新余公路段、都昌公路段及田波线 4 0km二级路改造工程边坡防护的推广应用 ,充分肯定了香根草等高植物篱技术“省工省钱省力、简便易行适用”特点。对香根草植物根系固土护坡力学试验结果表明 ,香根草根系平均抗拉强度达85MPa>假俭草 2 7 3MPa>白三叶 2 4 6MPa>莎草 2 4 5MPa>宜安草 19 7MPa>狗牙根 13 4MPa ,为香根草植物具有强大的固土护坡能力提供了力学理论依据。证明了经过试验示范→推广应用→理论检验的香根草等高植物篱护坡技术的科学合理性
Based on the demonstration project of science and technology in 1999 and the experiment of using vetiver contour hedgerows in the upper subgrade second-level road reconstruction project, in 2000, in the section of Xingguo Highway in Jiangxi Province, Xinyu Highway Section, Duchang Highway and Tian-Bo Line 40km two road reconstruction project to promote the use of slope protection, fully affirmed the Vetiver contour hedgerow technology “save money and labor-saving workers, simple and easy to apply” features. Roots of vetiver plant soil slope protection mechanical test results show that the average root mean square tension of vetiver 85MPa> centipede 2 7 3MPa> white clover 2 4 6MPa> sedge 2 45MPa> Yiancao 19 7MPa > Bermudagrass 13 4MPa, provided the mechanics basis for the strong ability of vetiver plant to protect slope from soil. It is proved that the scientific and rationality of Vetiver hedgerow slope protection technology after experiment and demonstration → popularization and application → theoretical test
