黄河小北干流放淤试验弯道溢流堰调度研究

Study on the Curve Overflow Weir Dispatch of the Exile Silt Experiment in Small North Branch of the Yellow River

运用水力学原理,通过输沙渠弯道溢流堰分水措施,人为控制泥沙的颗粒级配,形成泥沙的自然分选,将大部分直径>0.05 mm的粗泥沙淤积在淤区,把细沙重新排回黄河。

Using the hydraulics principle, through loses the sand ditch curve overflow weir water diversion measure, the artificial control silt pellet gradation, forms the silt the nature separation, is bigger than the majority of diameters 0.05 millimeter thick silt siltation in the silt area, returns to again the fine sand platoon the Yellow River.
