摘　　要：通州湾港区起步工程通过围填腰沙西侧近岸区域,开挖滩面形成一港池和二港池,呈U形。起步区支航道沿程具有粉沙质海岸特征,在当地潮流及波浪作用下,海床泥沙活动性较强,大风天航道易形成骤淤,可能影响大风浪过后的船舶进出港。通过对口门不同布置方案的研究比选,认为八字形方案可以较好地改善航行条件,减少口门段淤积。Through reclamation of the offshore area at the west side of Yaosha, the beach was excavated to form the first and second basins as U-shape in Tongzhou Bay Port＇s initial project. Initial area branch of the channel along the way with fine sand coast features, under local currents and waves, seabed sediment activity strong, channel easy to form sudden siltation in windy days, may influence the ship in and out after the storm. Through the research and comparison of different entrance layout schemes, we considered that the splayed layout plan can improve the navigation conditions, reduce entrance siltation.
