摘要:
为探讨植物篱措施下工程堆积体坡面不同坡段的减流减沙效益，选取了35，45，55 L/min放水流量，模拟0.3，0.4，0.5 mm/min的雨强条件，对24°坡度的堆积体边坡进行模拟径流冲刷试验。结果表明：植物篱可以很好地阻延坡面径流，且产流时间随着放水流量的增加呈线性递减趋势；对照坡面的平均产流量沿着水流方向呈先增后减的趋势，而植物篱坡面呈相反趋势；根据产流产沙量在不同坡段上的对比情况可知，植物篱措施的合理配置应着重加强中间坡段的防治；55 L/min流量下的累计减沙量显著大于另外两个流量的累计减沙量，累计减沙量与时间呈三次函数关系；时段产沙量随着时段产流量的增大而增大，二者呈幂函数关系；累计产沙量与累计径流量呈二次函数关系，累计产沙量存在最大值，且二者的函数关系存在定义域。该研究可为工程堆积体坡面防治措施的优化配置提供一定的理论支持。
Abstract:
The contributions of different types of plant measures and different spatial patterns to efficiency about runoff and sediment reduction are different. In order to investigate effect of hedgerow measure on the engineering accumulation slope of different slope segments of runoff and sediment reduction benefits, the flow rates of 35, 45 and 55 L/min were selected to simulate the rainfall intensity of 0.3, 0.4 and 0.5 mm/min, and the simulation of the 24 degree slope of the accumulation body slope was carried out. The results show that the hedgerow can delay runoff and runoff-yielding time with the flow discharge increase which presents linearly decreasing trend. The average runoff on control slope along the flow direction increased firstly and then decreased, hedgerow slope presents the opposite trend. According to the runoff and sediment yield in different slope sections, the rational allocation of hedgerow measure should focus on strengthening the prevention and control measures for slope of the middle section. The cumulative sediment reduction under 55 L/min flow was much higher than those of the other two flows, the cumulative sediment reduction and time follow the cubic functional relationships. The sediment yield increases along with the increase of the flow rate in the period of time, and the two had a power function relationship. Cumulative sediment yield and cumulative runoff follow quadratic function relationships. The total sediment yield include maximum value, and the function relation is defined. This study can provide theoretical basis for the optimized allocation of control measures on the engineering accumulation body slope.
