本文介绍了高水头船闸门顶缝隙流的１：１切片模型试验及其机理；阀门段廊道减压模型中的通气部位比较试验；门楣通气方式以及两座船闸门楣自然通气措施的实际应用情况。原型观测成果表明，门楣自然通气不仅可减免顶止水缝隙空化，而且可抑制阀门底缘空化，改善船闸运行条件。
In this paper, the 1: 1 slice model test and mechanism of the crevice flow at the top of a high-head ship gate are introduced. The comparison of aeration sites in the decompression model of the valve section corridor is carried out. The practical application of the aeration of the lintel and the natural aeration measures of the two lintel lintel . The results of the prototype observation show that the natural aeration of the lintel can not only reduce the cavitation in the top seal but also restrain the cavitation on the bottom of the valve and improve the operating conditions of the ship lock.
