摘　　要：受气候、河道等外界条件的影响,黄河内蒙古河段凌灾具有突发性强和破坏性强等特点,给黄河防凌带来很大的压力。位于黄河内蒙古头道拐河段的什四份子弯道,因受河槽萎缩、上游来冰量增加及河道形态等多重因素影响,每年极易成为初始卡冰位置。针对黄河内蒙古什四份子河段凌汛灾害频发、风险防控难度大等问题,基于实测河道地形和水深数据,并利用MIEK21的水动力模块和粒子追踪模块,构建了二者耦合的冰凌数值模型,对黄河什四份子河段冰凌演进情况进行了模拟分析,研究不同来冰量条件下冰凌的运动轨迹与流凌密集度,其结果揭示了黄河什四份子河段流凌运动规律。Influenced by external conditions such as climate and river channels,ice⁃run disasters in the Inner Mongolia section of the Yellow River are characterized by strong suddenness and destructiveness,which brings great pressure to ice prevention in the Yellow River.Especial⁃ly,the Shisifenzi bend in the Toudaoguai section of the Yellow River in Inner Mongolia is very easy to become the initial ice⁃run position ev⁃ery year due to the influence of multiple factors such as the shrinkage of the river channel,the increase of the ice volume from the upper rea⁃ches and the morphology of the river channel.In this paper,in view of the frequent occurrence of flooding disaster and the difficulty of risk prevention and control in the Shisifenzi section of the Yellow River in Inner Mongolia,based on the measured topography and water depth da⁃ta of the river channel and using the hydrodynamic module and particle tracking module of MIEK21,a coupled numerical model of ice⁃run was constructed,and a simulation analysis was carried out on the Shisifenzi River section of the Yellow River to study the trajectory of ice⁃run under the conditions of different incoming ice quantities and the densification of the ice.The result reveals that the ice movement law in Shisifenzi section of the Yellow River.
