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
