摘　　要：戴家洲河段是长江干线武汉—安庆段6 m水深航道整治工程最复杂的滩段之一,是实现6 m水深通达武汉的重难点河段。针对戴家洲河段6 m水深不足的问题,分析新水沙条件下戴家洲河段航道条件及变化趋势,提出治理思路、原则与工程方案。模型试验研究结果表明,整治工程实施后,戴家洲水道可以实现6.0 m×110 m×1050 m的建设目标,在不利水文年需实施少量维护性疏浚,为后续达到200 m航宽奠定基础。Daijiazhou waterway is one of the most complicated shoal segments in the 6 m-depth waterway regulation project at the Wuhan to Anqing section of the Yangtze River main line,and the difficult reach for the 6 m-depth waterway arrival to Wuhan.In view that the water depth of Daijiazhou reach is less than 6 m,we analyze the channel condition and changing trend of Daijiazhou reach under the new water and sediment conditions,and propose the regulation idea,principle and scheme.The result of the physical model experiment shows that Daijiazhou waterway can realize the construction target of 6.0 m×110 m×1050 m after implementation of the regulation engineering,and a small amount of maintenance dredging is required in unfavorable hydrological years to achieve the 200 m channel width in the future.
