摘　　要：针对黄河"82.8"洪水,运用模型试验手段研究在自然漫滩和控制漫滩条件下的黄河下游淤滩刷槽效果。通过对试验过程中实测的水位、流速、含沙量、泥沙粒径等多种水力泥沙要素及冲淤量进行分析,得出多种水力要素与主槽和滩区冲淤量的影响规律的关系式,并利用已有的实测数据对冲淤关系式进行验证。研究结论可指导不同来水来沙条件下,通过控制滩区来实现淤滩刷槽的目的。According to＂82.8＂flood, we conducted physical model test research on overbank flood silting in floodplain and scouring in main channel of lower Yellow River, and realized the effects of silting in floodplain and scouring in main channel under naturel floodplain and controlled floodplain conditions. A lot of flow and sediment elements were collected by the measurement system at the same time including stage, velocity, sediment concentration, sediment grain size and deposition-erosion was analyzed. The influence law and relation between the flow and sediment elements and overback deposition-erosion. According to the existing test data, we validated the relation. For the water and sediment from different area, this research be of guidance to will realize the goal of silting in floodplain and scouring in main channel through the use of controlling floodplain.
