中文摘要：

通过对人工破冰法、压缩空气吹冰法、电加热融冰法、水泵扰动破冰法、热管传热破冰法等5种方法的分析比较,得出水泵扰动破冰法是目前最可靠、最合理的水库闸门防冻的方法。研究开发了＂浮筒-索道＂式自动升降防冻装置,并实现了远方启停操作和运行状态监视,现场运行效果良好,为解决冬季高寒地区水工建筑物及弧门冰害问题提供了借鉴,具有良好的推广价值。

英文摘要：

Through the comparison on the five kinds of methods that are manually ice breaking,compressed air blowing ice,electric heating melting ice,water pump disturbing,heat pipe heat transfer,it was found that the water pump disturbing was the most reliable and reasonable method for preventing icing at the reservoir gate.The automatically lift/fall anti-icing device named ＂floating cylinder-cable＂ style device has been developed,the device could be operated and monitored in long distance away,the on-site running effect was well,it could be as reference for solving the icing problem for building and arc gates in severe cold areas in winter,and it has the value for development.
