摘要
北1#闸位于瓯飞一期围垦工程瓯江侧为I等工程,其外海侧潮差大,运行工况复杂。而水闸本身属低水头、低佛汝德数消能,消能率不高,故消力池型式的优化设计对大闸安全显得尤为重要。通过1∶50整体水工模型详细研究了无翼墙二级消力池的布置型式,对闸下消能方案进行了比选,并从水流流态、闸下冲刷等方面综合考虑,提出了适合该工程的消能布置型式,试验表明该布置型式可以有效地解决闸下水深不足时的水流衔接问题。
North Gate # 1 located on Oujiang side of Oufei first phase reclamation project, off the coast side large tidal range, complex operating conditions, sluice itself is low water head, low Froude number and energy dissipation rate is not high, so the optimal design of stilling basin type is very important for sluice safety. Detailed study the wingless wall two stilling basin layout pattern by the 1： 50 overall hydraulic model, compare and select the brake energy dissipation scheme, and integrated considering the flow pattern, under sluice scour etc., proposed the suitable energy dissipation layout pattern for the project. Tests showed that the layout pattern can effectively solve the water interface issues when the water depth is short under the gate, the research results can provide reference for similar projects.
