摘　　要：在我国新疆、西藏等西部高寒地区,抽水融冰是解决该地区引水式电站冬季运行冰害的理想措施。本文在对引水渠道冬季运行冰害形成过程及影响分析的基础上,结合新疆玛纳斯河流域红山嘴水电站应用抽水融冰情况,介绍了高寒区引水渠道冬季运行抽水融冰基本原理,并根据抽水融冰原型试验结果分析了抽水融冰的运行效果,给出了渠道水与井水混合后的温度变化过程以及渠道水温沿程变化规律等,进一步论证了抽水融冰理论的正确性和可行性。In the west alpine regions,pumping well water to melt ice（PWWMI） is an ideal method to solve the ice problem for diversion power station in winter.Based on the analysis of the process and effect on the ice problem in water diversion channel,combining with the applying situation of the PWWMI of the Hongshanzui Water Power Station in Xinjiang Manasi River Valley,the principle of the PWWMI was introduced.According to the prototype experiment results of PWWMI,the effect of the PWWMI was analyzed.The changing process of water temperature with well and channel water mixed,and the changing law along the channel were also obtained,which demonstrated the correctness and feasibility of the theory of PWWMI.
