摘　　要：通过模型试验分析斗笠子滩水流、泥沙运动特征,并对航道整治方案进行研究,提出了推荐方案。推荐方案工程实施后,整治效果良好,航道水流条件明显改善,船舶过滩能力增强,基本满足千吨级船舶自航上滩要求,表明对枯水卵石急滩实施"下抬上疏"的治理方案是行之有效的。Based on the physical model, we analyze the feature of flow and sediment movement and study regulation scheme. After project implementation, this plan has an immediate effect on basis of surveying thepractical ability of beach passing of ship. It can clearly be seen it is very effective to implement the scheme that the gravel rapid should be dredged at the upstream and reclaimed at the downstream on the dry rapids.
