摘要:
生态护坡技术逐渐广泛应用于边坡防护工程中,目前国内尚缺乏生态护坡水力侵蚀规律的研究。为更好地模拟自然降雨条件下Enkamat型生态护坡产流产沙规律,设置持续性降雨、间歇性降雨及变降雨强度不同降雨条件下试验,分析径流含沙量及泥沙累积侵蚀量随降雨历时变化规律; 设置降雨强度为120 mm/h,坡度25°下Enkamat7220+植被、Enkamat7020+植被、Enkamat7220+植被根系、Enkamat7020+植被根系、仅植被、仅根系、裸坡7组不同试验组次,分析并得出加筋植草型生态护坡产流产沙规律及其减流减沙特性,验证了Enkamat型生态护坡水土防护效果的优越性,为江苏沿海垦区生态软防护工程提供理论支撑。
Abstract:
Ecological slope protection technology is gradually widely used in slope protection engineering. At present, there's still a lack of research on water erosion law of ecological slope protection in China. In order to better simulate the law of runoff and sediment generation of Enkamat R ecological slope protection under natural rainfall conditions, experiments were conducted under different rainfall conditions with. The variation of runoff sediment concentration and sediment accumulation erosion with rainfall duration was analyzed. Seven different test groups of Enkamat R7220 + vegetation, Enkamat R7020 + vegetation, Enkamat R7220 + vegetation root system, Enkamat R7020 + vegetation root system, only vegetation, only root system, bare slope were set with the rainfall intensity as 120 mm/h and the slope at 25°. The law of runoff and sediment generation of reinforced grass-type ecological slope protection and its characteristics of water and sediment reduction were analyzed, the superiority of the soil and water protection effect of Enkamat R-type ecological slope protection was verified, which could provide theoretical support for ecological soft protection projects in Jiangsu coastal reclamation areas.
