Abstract: The Lingjintan ship lock is a single lift and moderate head ship lock with conveyance system of short culvert. Under normal operating conditions of the ship lock, the noise characteristics of each position in filling culvert are analyzed by the observation data in the prototype. It pointed out that under normal operating conditions of ship lock the noises in filling culvert are considered to be low frequency noises of non cavitation flow basically and in the noises there are not the high frequency components with higher energy accompanying strong cavitation.?

Key words: ship lock, conveyance system of short culvert, noise characteristics.

摘要： 凌津滩船闸为中水头单级短廊道输水船闸,本文就其原型观测资料分析了船闸在正常运行工况下输水廊道内的噪声特性,指出,在船闸正常运行工况下输水廊道各部位的噪声基本上均属非空化低频流动噪声,不存在伴随强空化出现的具有较大能量的高频成分.
