| 摘 要： | 旁海船闸输水阀门采用平板阀门形式，其工作水头达23.0 m，阀门顶初始淹没水深仅7.5 m，阀门水力学问题是该船闸水力设计较为关键的技术难题。通过物理模型试验研究，提出突扩廊道体型，优化阀门门体结构和门槽体型，探讨阀门段水力特性和空化特性。研究表明，在优化阀门门体结构和门槽形式的基础上，通过突扩廊道体型、门楣自然通气保护（必备措施）和跌坎强迫通气保护（储备措施）可有效解决该船闸平板阀门空化问题。

| Abstract: | The gate type of Panghai ship lock is flat,and the working head is 23.0 m.The initial submerged depth of gallery roof is only 7.5 m,and the hydraulic problem on the flat gate is the key technical problem in hydraulic design.Based on physical model researches,twe propose to expand the corridor,optimize the gate structure and corridor structure,and discuss the cavitation and hydraulic characteristics.Research shows that,cavitation problems could be solved on the basis of optimizing the gate structure and corridor structure,applying the techniques of extended corridor type,and take the necessary measure,natural aeration by lintel,and reserve measure,forced aeration by the drop floor. |
