摘　　要：为了预防冰冻灾害对水闸闸门的破坏,制定合理的防冻策略,在分析现有结冰预报模型的基础上,提出利用FENSAP-ICE软件分析水闸表面结冰过程,研究凝冻天气水闸积冰生长过程和冰层在水闸表面的分布特征。研究结果表明,空气中的过冷液体容易在闸门和门槽连接处聚集形成积冰,并从闸门底部沿两侧门槽向上生长,应采用闸门化冰与门槽挡风避雨相结合的水闸防冻策略。In order to prevent the damage of sluice gate caused by freezing disasters and to draft proper anti-freezing measures,based on an analysis of the existing freezing prediction model,FENSAP-ICE software was used to analyze the freezing process on the sluice surface,and to study the growth process of ice accretion as well as the distribution characteristics of ice cover on the sluice surface in freezing weather.The results of study show that the supercooled liquid in the air likely accumulate and form ice at the junction between the gate and the sluice groove.The ice would grow upward from the bottom of the gate along both sides of the sluice groove.The anti-freezing measures of sluice should combine ice melt on the gate with shelter the groove from rain.
