摘　　要：针对内河航道中桥群河段船舶通航安全问题,以浏阳河汉桥工程所在的桥群河道为例,基于浅水方程,建立了浏阳河二维水流数学模型;基于MMG方程,建立了船舶操纵运动数学模型。通航水流条件分析表明:汉桥修建对桥群河段水流的影响较小,河道水流平顺,对船舶安全航行的影响较小。船舶航行模拟分析结果表明:船舶可顺利通过桥群河段,且操作较容易,为桥群河段的通航安全提供了科学依据。The primary objective of this study,which is based on the Han Bridge in Liuyang River,was to investigate the navigation safety of the ship in inland waterway bridge river group.The mathematical model of two-dimensional flow and the ship's manipulating motion is established using the shallow water equation and MMG equation.The analysis of navigable flow conditions shows that the Han bridge has little effect on the flow of the bridge group,and the ship was slightly influenced by the bridge.The results of the ship navigation simulation show that the ship can pass steadily through the bridge river group,and the operation is easier,which can provide a scientific basis for the navigation safety through the bridge group.
