摘要
阀门空化问题是高水头船闸设计中最为关键的技术难题。门楣和底缘空化特别严重时,会引发"声振","声振"会导致阀门面板及廊道混凝土剥蚀,严重影响工程安全。依托实际工程研究阀门防空化措施,取得了满意的成果。所采用的研究方法及措施具有普适性,可供相关工程参考借鉴。
Valve cavitation problem is the most critical technical problem in the design of high-head lock. Serious cavitation of the lintel and the hemline will arise the ＂vibroacoustic＂ phenomenon, which will lead to denudation of valve panel and corridor concrete, and thus seriously affect the engineering quality and safety. The cavitation defense measures for the lock valve are researched based on the actual engineering and satisfactory results are obtained.The research methods and measures are applicable to most cases, so they may serve as reference for the similar engineering.
