南运河冬季输水冰情及对策研究

Ice Condition in Winter and Countermeasures during the South Canal

南运河的冬季输水工作开展较少,冰期输水经验不足。2022—2023年度,南水北调东线北延输水为线路启用以来首次冬季输水。输水期间,在南运河段设立安陵、北陈屯2个观测站点,对冰期输水各个阶段的冰情特点进行观测,从而了解并掌握冰情的变化规律,并提出冰期输水对策,为今后的冰期输水工作提供参考。

The winter water conveyance work of the South Canal is less carried out,resulting in insufficient experience.The northern extension of the eastern route of the South-to-North Water Diversion Project in 2022-2023 is the first winter water conveyance since the line was put into operation.During the water conveyance period,two observation stations,Anling and Beichentun,were set up in the South Canal section to observe the characteristics of the ice regime at each stage of water conveyance during the ice period,so as to understand and master the changing law of the ice regime.In this paper,the ice conditions and the water transportation countermeasures in the northern Yannan Canal section of the eastern route of the South-to-North Water Transfer Project are studied,providing reference and suggestions for the water transportation in the ice period in the future.
