摘　　要：针对黄河包头画匠营子河段取水问题，研究水沙变化复杂河段动床河工模型试验设计中的一些问题与数值计算方法。文中着重探讨了起动流速比尺、悬沙和底沙比尺的确定方法，详细给出了二维非恒定流及非平衡输沙的数值计算方法。试验及计算结果与原型河段实测资料吻合较好。Some problems and value calculation method in test design of moved river bed model in the reach with varying water and sediment were inquired in this paper in accordance with the water fetching problem in Huajiangyingzi reach of Baotou City of the Yellow River. The paper probed into the determination method of starting velocity scale, suspanded sediment scale and botom sediment scale in particular, and put forward the calculation method of values of two-dimensional non-fixed flow and non-balanced sediment transportation in detail.Tested and calculated results well coincided with actual data in the reach.
