摘　　要：以沉沙池物理模型试验资料为依据，探讨了沉沙池内悬移质含沙量及淤积物粒配的沿程变化规律，给出了淤积百分数与入口含沙量之间的经验关系式，并利用超饱和输沙数学模型对实测数据进行了对比计算。The settling basins is one of the important engineering installation for the disposal of engineering sediment.Its shape,slope and exit elevation are related directly to the laws of the sediment movement and the characteristics of the sediment deposit.According to the experimental data about physical model of the settling basins,this paper investigated the laws of the sediment sorting along the longitudinal of the settling basins and calculated the changing of the sediment concentration and the sediment grading by means of mathematical model.The results of calculation show that the theory of the supersaturation transport sediment can be used to describe the sediment movement prosess of the settling basins,on the condition that the parameters are selected reasonably.
