摘　　要：针对华南地区高速公路红黏土边坡抗冲刷性差、水土流失严重、植物种子易流失等问题,通过正交试验,对基于W-OH的土壤改良方法和基于人造壤土的土壤改良方法进行分析,得到最优基材配比。提出两种改良方法的设计方案,并在惠清高速公路TJ5标现场应用,结果表明:两种土壤改良技术,均能有效提高红黏土边坡的土壤养分、根土复合体力学性能和抗蚀性。At the red clay slope along highway in south China,there exist poor scour resistance,severe water and soil erosion,plant seeds easy-to-lost and other problems.Hence orthogonal test was carried out to analyze the methods for soil improvement based on W-OH and based on artificial loam,and to get the optimal proportioning of base materials.Two design schemes of improvement were proposed,and applied to the section TJ5 of Huizhou-Qingyuan Highway.The result shows that the two techniques for soil improvement may increase the soil nutrient at the red clay slope,and the mechanical property and erosion resistance of the root-soil composite.
