中文摘要：
对高速公路生态护坡工程开展试验观测。研究探讨生态护坡技术的水土保持效应。结果表明，在高速公路高陡边坡上采用生态护坡技术建植草本植被。在短期内可完全覆盖坡面，水土保持效果显著，可抑制边坡侵蚀的发育，有效控制坡面沟蚀的发生，在中雨到暴雨的情况下，边坡径流系数在15．97％以下，土壤流失量极小。生态护坡技术的水土保持机理主要与草本植被对降雨的截留、雨滴能量的削减、坡面径流的抑制、根系的锚固与加筋作用，以及生态护坡技术本身的工艺特性有关。
英文摘要：
Monitoring was carried for a slope protection project in highway to survey the soil and water conservation effects through bioengineering techniques for slope protection. The results indicated that through bioengineering techniques for slope protection such as herbs planting, the foliage can cover the whole high and steep slopes in the highway and get significant soil and water conservation effects. The development of soil erosion could he controlled and gully erosion were rarely happened on slope protected with bioengineering techniques. Moreover, the mean runoff index is lower than 15.97% and soil erosion mass is rather low on the protected slope under mediumheavy rain and hard rain. The slope protection mechanism of bioengineering techniques was analyzed. The soil and water conservation effects is closely in relation with vegetation interception, power reduction, controlling of slope runoff, root anchorage and reinforcement etc. , and also property of bioengineering techniques for slope protection.
