摘　　要：通过模拟斗槽预沉池中泥沙冲淤的试验 ,研究了在重力和紊动扩散共同作用下悬移质泥沙运动的有关特性 .解决了实际斗槽运行中存在的泥沙冲淤效果问题 ,进而提出相应的运行技术条件和一些必要的工程改进措施 ,满足了厂方所要求的斗槽运行功能 。By means of model experiments of sediment deposition and wash , the characteristics of suspended sediment movement under the action of gravity and turbulent diffusion are studied in this paper, and some problems concerning sediment deposition and wash in the prototype lateral canal are solved. Meanwhile, some technical conditions and engineering measures are proposed. Therefore ,the required working functions of the lateral canal are realized.
