摘　　要：为解决散乱浅滩弯曲河段水流条件复杂、船舶航行困难且易受浅水效应影响的问题,建立平面二维水流数学模型及船舶操纵运动数学模型,以湘江株洲枢纽库尾鱼弄子滩为例,通过实测资料验证数学模型的可靠性,对典型工况进行船舶运动数值模拟,计算相应航行参数,评估航道整治效果及通航条件。结果表明:疏浚受散乱浅滩影响的弯曲航道能有效优化航道水流流态,明显改善船舶通航条件。该数值模拟可为评估散乱浅滩弯曲航道的整治效果提供科学依据和指导。In order to solve the problem of complex water flow conditions in scattered and shallow shoals,curved river sections,difficult ship navigation,and susceptibility to shallow water effects,a two-dimensional mathematical model of water flow and a mathematical model of ship maneuvering motion are established.Taking the Yunongzi Shoal at the tail of the Zhuzhou Hub on the Xiangjiang River as an example,the reliability of the mathematical model is verified through field measurement data.The numerical simulation of ship motion under typical working conditions is conducted to calculate the corresponding navigation parameters and evaluate the effect of channel improvement and navigation conditions.The results show that dredging curved channels affected by scattered and shallow shoals can effectively optimize the water flow pattern,and significantly improve ship navigation conditions.The numerical simulation can provide scientific basis and guidance for evaluating the regulation effect of the crooked channel in scattered shoals.
