摘　　要：交叉河口淤积影响船舶正常航行,易发生搁浅事故。为充分发挥航道的航运功能,应及时分析碍航原因,制定航道疏浚方案,确保航道通航顺畅与安全。以通扬运河与泰东河交叉河口为研究区域,构建二维Delft 3D水沙模型,结合实测分析其泥沙运动规律与地貌演变特征。基于不同疏浚高程和疏浚边坡设计6个航道尺度方案,并通过模拟分析得到兼顾过往船舶航行安全和疏浚经济成本的优化方案。本研究可为类似交叉河口的航道尺度设计与优化提供借鉴。Deposition at cross estuary affects the normal navigation of ships and leads to grounding accidents.In order to make full use of the navigation function of the waterway,it is necessary to analyze the causes of navigation obstruction in time and formulate waterway dredging plans to ensure smooth and safe navigation of the waterway.This study takes the cross estuary of Tongyang Canal and Taidong River as the research area,and establishes a two-dimensional Delft 3D water-sediment model to analyze its sediment movement law and geomorphic evolution characteristics in combination with the actual measurement.Based on different dredging elevation and dredging slope,six channel scale schemes are designed,and through simulation analysis,an optimization scheme that takes into account the navigation safety of passing ships and the economic cost of dredging is obtained.This study can provide reference for the channel scale design and optimization of similar crossing estuaries.
