摘　　要：漏斗式全沙排沙设施是一种排沙耗水量小 ,截沙率高的泥沙处理技术 ,并已在工程实际应用中取得了良好的效果。本文通过其清、浑水流场特性分析表明 。It is a typical 3\|D spiral flow inside the sand funnel.The tangential velocity sustains the vortex intensity of flow in the sand funnel,the radial velocity is benefit to sediment moving to the centre and the axial velocity is benefit to the sediment sinking,so the sand funnel is successful in sediment disposal.Prototype observation of the sand funnel project of Hongshanzui hydropower station shows that the sand funnel passesses many advantages,such as high sand interception rate,and little water consumption,etc.It could be widely used in practice.
