摘 要:由于船闸存在原模缩尺效应,且桂平二线船闸规模巨大并采用了新型消能措施,为了解其输水特性,保障船闸高效安全运行,通过现场观测与实船试验等手段,对桂平二线船闸输水水力特性、船舶停泊条件及桂平双线船闸间相互影响等进行了详细的观测与分析。结果表明:现有运行方式和推荐运行方式下,二线船闸各项水力指标均能基本满足规范和设计要求,但二线船闸泄水对一线船闸闸门有一定影响,并须重视超灌泄对闸室船舶停泊安全的影响。Due to the scale effect between the model and prototype of ship lock, the huge dimension and the new type energy dissipation measures of the Guiping second lane lock, for knowing the actual hydraulic characteristics and guaranteeing the safety and efficiency of the lock, by prototype observation and full scale ship test, we observe and analyze the hydraulic characteristics, ship berthing conditions and also the interaction effect between the first and second lane lock. The results indicate that: under the current operation mode, each hydraulic characteristics of the second lane lock can basically satisfy the demands of the standards and design, but there will be some influences on the gate of the first lane lock when the second lane lock is emptying. More concerns shall be given to the influence of the overshooting on the ship's berthing safety.
