Abstract
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.关键词
