摘　　要：南通港通州湾港区一港池进港航道的建设主要依托辐射沙洲南缘的小庙洪水道。针对该航道口门航段水流条件复杂、航道回淤较大的问题,提出在一港池口门处建设双导堤,以起到防沙、导流的目的。防沙堤采取高潮位整治,堤顶高程取设计高水位,堤头局部逐渐降低至滩面附近。数值模拟和回淤预测表明,防沙堤的建设能起到较好的改善口门流态、减小口门航段淤积的效果。The channel construction of the first harbor basin in the Tongzhou Bay of Nantong Port mainly relies on the Xiaomiaohong channel in south margin of the radial sand ridges. As the complicated flow conditions and high siltation at the entrance section of the channel, a double-dyke is proposed to construct at the entrance of the channel, which main function is sediment prevention and diversion. The high tide level regulation is adopted for the sand dyke, the elevation of the sand dyke is taken as the design high water level, and the local elevation of dyke heads is gradually decreased to beach face. The numerical simulation and siltation prediction show that the construction of the sand dyke can improve the flow conditions and reduce the siltation at the entrance section of the channel.
