五强溪水电站高水头船闸输水系统动水压力与反向弧门流激振动

Hydrodynamic pressure acting on wall of filling emptying system and flow induced vibration of reversed tainter gate for high lift ship lock

本文介绍了五强溪船闸二闸首于１９９６年１２月１２日～１３日进行的原型观测成果与分析．着重从高水头船闸输水系统不恒定流压力瞬态变化和反向弧门流激振动两方面，分析输水廊道突扩体发生空化空蚀的可能性，以及反向弧门流激振动的危害程度，并对其安全运行作出评估．

In this paper,the analysis results of prototype observation data for high lift ship lock in Wuqiangxi hydro project is presented.Emphases are laid on the distribution of hydrodynamic pressure acting on the wall of filling emptying system and flow induced vibration of the reversed tainter gate.The possibility of cavitation and the safety of the gate are assessed.
