南水北调典型倒虹吸防冰塞安全运行试验

An experimental study on ice jam prevention of typical inverted siphon for South-to-North Water Diversion Project

  • 摘要: 研究倒虹吸等局部水工建筑物的防冰塞安全运行条件对于南水北调输水工程的冰期安全运行有着重要的意义。通过真冰条件下的倒虹吸冰水动力学试验,模拟了不同水力条件时冰块在倒虹吸进口前的堆积和演变过程,得到了倒虹吸防冰塞安全运行时各相关水力参数间的关系。根据实验结论对南水北调中线工程京石段倒虹吸的冰期输水能力和调控进行了分析,为该输水工程倒虹吸冰期的安全运行提供参考。

     

    Abstract: For the safe operation of South-to-North Water Diversion Project, ice jam prevention of inverted siphon and other partial hydraulic structures is very important during the period of an icing event. The ice jam process at the entrance of inverted siphon is simulated by ice-hydrodynamics experiments under real ice conditions. The hydraulic conditions of ice jam prevention are obtained. Using the experimental data, the water diversion capacity and control regulations of inverted siphons for the Beijing-Shijiazhuang section of South-to-North Water Diversion Project are analyzed. This study provides a valuable reference for the safe operation of the project during the period of an icing event.
