| 摘 要： | 应用河流动力学和热力学等原理,建立了冰塞形成及演变发展的冰水耦合的综合动态数学模型,并利用黄河河曲段原型实测资料进行了验证,同时对冰塞体厚度和水位的演变规律进行了研究分析。计算结果表明:提出的数值模型能较好地模拟河道封冻过程中冰塞体的发展演变过程。

| Abstract: | Based upon the theory of river mechanics, thermodynamics and late research results on the mechanism of ice jam, this paper presents a synthetic and dynamic mathematic model for river ice-jmn sunulation, characterized by ice-water coupling, which describes formation, evolution and evolvement of river ice-jam, The model is validated by the measurement data on the Hequ section of the Yellow River. |

| Keywords: | river ice jam river ice regime ice run numerical simulation river ice hydraulics |
