摘要
以消浪固土为护坡目标,通过设计一种串珠式柔性护坡构件,在水陆交界面形成一个连续的波浪缓冲带,降低波浪冲刷力,保护消落带表层土壤。并在构件栽植孔中种植牛鞭草、狗牙根、香根草等水土保持植物,有效发挥植物根系的固土护坡作用,从而实现生物-工程相结合的消落带库岸防护。该技术具有稳定性高、适应性强、消浪作用好以及环境友好的特点,可显著减轻波浪对消落带坡面的侵蚀作用,保护消落带土壤,美化消落带环境。
For the purpose of wave reduction and soil erosion in the reservoir drawdown zone, a beaded linking and flexible slope protection component was designed. The component,lying in land and water interface to form a continuous wave buffer zone, can reduce wave erosion force and protect the topsoil of water level fluctuating zone. Whilst soil and water conservation plants ( i. e. Hemarthria compressa, Cynodon dactylon, vetiver grass) are planted in the planting hole of construction, roots play the effectively role to increase slope stability. Due to high stability, adaptability, good wave dissipation effect and envi- ronment friendly, the bio-engineering combining technology can significantly mitigate wave erosion in the drawdown zone, and then retain soil and conservate landscape environment.
