【 摘 要 】

Since the water transfer in the winter from the Project of Diversion from Yellow River to Qingdao is affected by the cold air flow in the north, the surface of the channel water body is prone to icing. In the process of water conveyance, ice accidents such as ice icicles, ice jams and ice dams often occur, causing serious damage to hydraulic structures such as pumping stations, gates, and channel side slopes along the line, it not only affects the safety of water delivery, but also affects the efficiency of water delivery. In view of the local meteorological conditions and the characteristics of the channels in the Shouguang water conveyance section, this paper proposes the method for water conveyance by using the deep water temperature of the Shouguang Shuanghuangcheng Reservoir for ice-free water conveyance, calculating the change of water temperature and channel non-freezing length during water conveyance based on water body heat balance theory, providing the new ideas and theoretical basis for solving water transport problems in the winter.
