摘　　要：平板闸门多用于事故闸门或检修闸门,很少用于工作闸门进行局部开启控制泄流,因局开控泄过程中易引起闸门的振动和门槽空蚀等问题。受施工布置、工程地质条件和运行方式等方面影响,有些工程须采用平板闸门进行控泄。通过专门的试验研究,分析闸门的振动特性和门槽空蚀空化特性,为闸门运行安全提供可靠依据。Due to such problems as vibration of the gate and cavitation of the gate slots during the partial opening control release process,plane gates are mostly used for accident gates or maintenance gates,and rarely used for working gates for partial opening and controlled release.Affected by construction layout,engineering geological conditions and operation mode,some projects need to use plane gates for controlled release.This paper analyzes the vibration characteristics of the gate and cavitation erosion characteristics of gate slots through a special test and research,and provides the basis for safe operation of the gate.
