Abstract: The hydrodynamics of hoisting vertical ship lift is a complex subject,in the past it was rarely studied at home and abroad. For more than ten years recently,through the model experiment studies on the hydrodynamics of Three Gorges ship lift,especially from the two large scale overall model experiments of Shuikou ship lift in Fujian province and Yantan ship lift in Guangxi province,the authors accumulated more materials and data. In this paper research achievements of above mentioned model studies were summed up, comparatively systematic analyses and introductions about the hydraulic characteristic values of vertical ship lift during operation,such as the longitudinal eccentric moment formed by the water mass wave in chamber,stability of ship chamber,maximurn subsidence of ship going into chamber,maximum water surface rise in chamber pond of the put in water type ship chamber during launching process,the working conditions of opening tumble gate etc.,are presented also.
