| 摘 要： | 基于试验数据对增强长江口北槽航道内水流冲刷能力进行探讨，结果表明：试图仅通过实施丁坝工程来调整北
槽中段地形使天然深泓与目前航道轴线位置吻合是行不通的；若要达到较显著的冲刷效果，新建丁坝宜布置在靠近主流的
深水区，此外在北槽中段北侧加密丁坝亦有显著作用；若想进一步增强北槽中段航道内的水流冲刷能力，宜综合采取新建
丁坝工程和航道轴线调整的措施，仅仅依靠加长丁坝，很难较好地增强该段航道内的水流冲刷能力。

| Abstract: | Based on the test data, the engineering measures to enhance the flow erosion capability in the north
passage of the Yangtze estuary are discussed. The results shows that: 1) It is not feasible for attempting to adjust the
topography in the middle region of the north passage to make natural thalweg location coincident with the current
navigation channel axis by dike construction project only; 2)To achieve a more obvious erosion effect, the new dike
should be arranged in the deep water near the mainstream, in addition, groyne encryption also plays a significant role
in the north side of the north passage, middle region; 3) To further enhance the flow erosion capability in the north
passage, the comprehensive measures of adjusting new groyne and navigation axis should be taken. It is difficult to
better enhance the flow erosion capability in the north passage by extending groyne only. |
