摘要
在宽浅式河道上修建穿河倒虹吸工程,行洪口门宽度是影响建筑物投资和安全的决定因素。结合沧河渠道倒虹的工程情况,在数值计算基础上,运用河工模型试验,对穿河工程附近河道的壅水和冲刷进行研究,采用670m口门宽度方案。对同类工程设计具有一定的参考价值。
When the inverted siphon project is constructed on the wide-shallow channel, the width of the opening for flood discharge is a determinative factor to affect the investment and safety of the structure. Base on the construction of the Canghe River inverted siphon project, the effects of the riverbed backwater and erosion are described by a hydraulic model after mathematics calculation, and alternative plan with the opening width of 670 m is adopted, which provide some reference for the similar projects.
