Abstract: Various kinds of water compensating state of Three Gorges ship lock are discussed in this paper firstly. By means of model test and numerical calculation, several hydraulic problems in water compensating operation of the lock, such as loss in filling and emptying system, process of filling and emptying discharge, process of water level, filling and emptying time, water compensating discharge and operation step of water compensating valve are studied in this paper also.
