摘要
通过对严寒寒冷地区宽浅式渠道冰水二相流的运行方式下渠道水体温度的变化及分布规律的研究，探讨现有渠道长时间（全冬季）长距离或有效延长供水时间实现安全通水的可行性，为渠道的安全运行提供最基本的技术支撑，该分析成果可为在西北严寒及寒冷地区冬季渠道冰水二相流的运行方式提供一定的经验和参考。
In this paper, the change and distribution law of wide-shallow channel water temperature field under ice-water two-phase flow opera- tion mode in cold and severe areas are studied. And the feasibility of long distance safety water conveyance using existing channel in long time （whole winter） or effective prolonged water conveyance time is also discussed. It will provide basis theoretical support for channel safety operation. The analysis results will provide experience and reference for winter channel operation under ice-water two-phase flow in North-West severe and cold areas and cold areas.
