摘　　要：阐述了螺旋管流中泥沙“旋浮”的机理 ,运动轨迹 ,含沙量分布 ,挟沙力及能耗诸方面的理论分析与试验结果 ,并讨论了它与悬浮的关系 。A theory of sediment floating in pipe spiral flow was proposed. Through theoretical analysis and comparison with experimental results the trajectories of sand particles, the distribution of sand concentration, the silt carrying capacity and the energy consumption were examined, and the relationship between suspension and floting in spiral flow was discussed.
