摘要
利用水槽进行了粗细两种泥沙的高含沙水流稳定输送试验,在此基础上就浑水分流对高含沙输送的影响进行了试验研究。浑水分流后,一般会改变水流的含沙量,或者影响水流的稳定输沙状态,引起河床的冲淤变化。分流会增加水流含沙的浓度或造成淤积,从而影响高含沙水流的稳定输送。
Sediment transport capacity of hyperconcentrated flow is affected by the factors such as cross section, channel slope, water diversion, and so on. Experiments were carried out to study the influence of water diversion on the sediment transport capacity. Siltation occurs due to water diversion and the rate of sediment siltation is proportional to the ratio of water diversion, the ratio between sediment particle size ond water depth, and the concentration ratio between course particles and fine particles.
