摘　　要：根据三峡水库下泄曲线,在动床模型上,预测了三峡不同运用阶段宜昌河段冲淤变化和水位降落情况;研究了防止河床冲刷的工程方案。结果表明,潜坝方案能够满足三峡不同运用阶段的葛洲坝三江下航道通航水位要求,该方案经济可行,效果显著。On the basis of outlet curve of the Three-gorge Reservior,the process of lowering of water level and changees of scouring and silting of Yichang Reach were predicted on the movable-bed model,and the different layouts to resisit the erosion were studied.The result shows that the plan of submerged groin can meet the demands of navigation water level of Sanjiang Channel downstream Gezhouba Dam,during the diffirent construction periods of the Three Groges Project.
