摘　　要：基于能量守衡原理和水动力学的方法 ,探讨了多沙河流河工动床模型人工转折设计原理、原则和方法 ,并给出了黄河下游河道河工动床模型的设计实例。通过设计率定试验表明 ,所提出的河工动床模型人工转折设计方法 。Based on the principles of energy conservation and hydrodynamics, the design principle and method of artificial transition on movable model of river engineering in the sediment-laden river has been discussed and the design example in the lower Yellow River was presented. It is shown through design calibration experiment that the design method of artificial transition on movable model of river engineering can ensure the hydraulic law of flow being in agreement with deformation of channel's erosion and deposition before and after the channel transition of model.
