摘　　要：分析了水流越过航道的变化,考虑了航道深度、宽度、水流与航道交角等因素对航道回淤的影响,提出了开敞航道回淤计算公式。计算结果与现场实测、数模和物模的结果很接近。From analysis of the pattern of flow when it obliquely crosses the open channel,a practical formula for calculating siltation in the dredged channel was presented,conidering the effects of the channel depth and width as well as the intersection angle between flow and channel on siltation.The calculated results are in good agreement with those from field observation,math model and physical model.
