摘　　要：为进一步提升护坡工程抗风化、抗冲刷能力,削减边坡的承载压力,研究设计了一种结合三维网防护技术与混播的生态护坡方案,并对其进行效果评价。结果表明,研究区域D(高羊茅+狗牙根+铺设三维网)虽然植被覆盖度相对较低,但土壤侵蚀量最小,径流系数最高;黏聚力和内摩擦角分别为43.2 kPa和31.2°,对比对照组和素土对照组,都有很大的提升;高度适宜、抗逆性强,均一性最好。研究提出的基于三维网防护技术与混播的生态护坡方案在水土保持、景观持久性、生态适应和经济成本上具有良好的效益。Slope protection engineering is the construction of facilities that carry out paving and planting operations around the slope to prevent erosion of water conservancy facilities.To further enhance the weathering and erosion resistance of slope protection engineering,reduce the bearing pressure of slopes,a ecological slope protection scheme combining three-dimensional network protection technology and mixed seeding was studied and designed,and its effectiveness was evaluated.The results showed that in study area D(tall fescue+dog tooth root+laying three-dimensional network),although the vegetation coverage was relatively low,the soil erosion was the smallest and the runoff coefficient was the highest;The cohesive force and internal friction angle were 43.2kPa and 31.2°,respectively,which showed a significant improvement compared to the control group and the plain soil control group;Highly suitable,with strong resistance to stress and the best uniformity.The ecological slope protection scheme based on three-dimensional network protection technology and mixed planting proposed in the study has good benefits in soil and water conservation,landscape persistence,ecological adaptation,and economic cost.
