针对黄河泥沙多且变化大的特点 ,采用泥沙运动相似条件的最新研究成果 ,完成了黄河包头河段动床模型沙选择和比尺设计。利用原型实测资料进行的验证试验 ,表明模型小河较好地复演了原型河势、水沙运动规律及河床冲淤变形等。 According to the characteristics of the Yellow River sediment with many changes and great changes, using the latest researches on the similar conditions of sediment movement, the model selection and scale design of the movable bed model in the Baotou reach of the Yellow River have been completed. The verification test using the prototype data shows that the model river is a good example of the original river regime, the law of water and sediment movement and the river bed scouring and silting deformation.
