摘要
介绍了旋转环形水槽的结构和工作原理,提出了削弱环形水流离心力的方法,通过环形水槽中周期往复流泥沙运动试验得出水体含沙量与床面剪切力和水体挟沙力之间的关系。
The structure and principle of rotary ring flume is introduced.The method of weakening centrifugal force in the rotary ring flume is proposed and sediment movement under the effect of periodic reciprocating current is tested in the ring flume.The relationship between sediment concentration,shear stress and silt-carrying capacity is obtained.
