摘要
南水北调中线输水渠道的沿程流量变化需要对节制闸进行调控,由此会产生非恒定流的水力现象,引发水面的骤然升降,这将会对工程设计和输水安全造成影响。选取典型渠段设计物理模型,采用波高传感器量测各种工况下渠道内水位的变化。同时也通过数值计算模拟了渠道水深的变化,与试验结果进行了比较,文章结论对工程设计具有参考价值。
In the Middle Route Project (MRP) for South-to-North Water Diversion the controlling gate of conveyance channel should be applied to adjust the discharge along'the route. The change of gate opening would cause the phenomenon of the unsteady flow which is characteristic of the rapid fluctuation of water level. It would effect the project design and the security of water transmission. According to the typical conduit a hydraulic model is designs to measure the variation of the water depth in appliance of the wave-height gauge on certain working conditions. Moreover, the paper utilizes the numerical method to imitate the variation of the water depth and compares it with the experimental value. The conclusion is valuable to the project design in reference.
