摘　　要：主要介绍了新疆红山嘴水电站应用抽水融冰技术解决长期困扰水电站运行的冰害问题,给出了高寒区引水渠道冬季运行抽水融冰基本原理。根据原型观测结果,分析得出了抽水后渠道水温的沿程变化规律。参照经验公式对不冻长度进行了计算,并将结果与2级引水渠上布置的融冰井间距作了对比,为抽水融冰井群优化布置等相关内容研究奠定了基础。This paper mainly introduces the application of pumping melting technology to solve the problem of ice that has plagued hydropower station operation for a long time in hongshanzui hydropower station,xinjiang.And first the basic principle of pumping water melting ice at diversion channel is proposed in dry cold plateau.According to the results of prototype observation,the rule of water＇s temperature varies along the channel after well water is pumped.And the non-freezing length is calculated by referring to the empirical formula.All the research provides the basis for the optimization of pumping melting wells and other related research.
