引黄济青倒虹吸水工模型试验研究

以弥河倒虹为例。通过水工模型试验，研究了引黄济青工程倒虹进口的水流流态、水头损失、挡冰性能等问题，并论述了倒虹吸设计中进口布置对水流条件的影响。指出：平原地区倒虹的水头损失不大；形成冰坝的决定性因素是水面流态；为消除通气槽中的水面震荡现象，应将通气槽改为通气孔；为避免发生水跃，应取消设置沉沙池。

Test and Study on Inverted Siphon Hydraulic Model of Diverting the Yellow River Water to Qingdao

The paper studies the issues of flow regime,head loss and ice retaining performance of the intake of inverted siphon of the Yellow River Diversion Project to Qingdao and discourses upon the influence of the intake layout to flow condition by taking inverted siphon on the Mihe River as an example and through hydraulic model tests.It points out that the head loss of inverted siphon in plain area is not much;the determiner of forming an ice dam is surface regime;it should change aeration slot into vent for removing surface commotion and;it should annul desilting basin for avoiding hydraulic jump.
