摘　　要：某工程孔板洞和排沙洞弧门设计水头分别达到140 m和122 m,高水头引起高压力、高流速,为了有效排沙,要求闸门频繁局部开启,由此给该工程弧门结构设计带来一系列研究课题。笔者结合该工程事故闸门的原型动水闭门试验情况及产生原因进行详细介绍、分析,对泄水建筑物的通气孔设施设计提出建议。The design water head is 140 m for the gate of orifice tunnel and 120 m for that of desilting tunnel of a project. High water head results in high pressure and high flow rate, and gates shall be often partially opened for effective desilting. Therefore, a number of issues shall be studied in structural design of the gate. This paper studies the prototype closing test in flowing water for emergency gates of the project and the causes, and provides suggestions for design of air holes of water release structures.
