Abstract: The main dam and the auxiliary dam of Huangbizhuang reservoir are long. Every winter, the dam slope is damaged by the freezing of reservoir water, thus the freezing damage prevention is an arduous task. Based on the failure process and its characteristics of ice jam at Huangbizhuang reservoir, the ice pressure effect is analyzed. As well, its hazard prevention and countermeasures are proposed and implemented. Years of operation shows that the prevention and countermeasures of ice jam for Huangbizhuang reservoir are of good effect and of significant engineering application value.

Key words: ice jam, ice push, ice pull, countermeasure

摘要： 黄壁庄水库主、副坝较长，每年冬季坝坡受库面冰冻破坏，防冰冻破坏任务艰巨。根据黄壁庄水库冰壅破坏过程及其特点，对冰压力作用进行深入分析，有针对性地提出并实施冰壅危害防治措施。多年运行表明，黄壁庄水库冰壅危害防治措施效果显著，有良好的工程应用价值。
