摘　　要：三峡船闸末级闸室泄水和大坝泄洪引起下游引航道水位波动，水流往复运移。这种非恒定流影响船舶在引航道安全航行和停泊。通过物理模型试验介绍了船闸下游引航道非恒定水流特性和通航水流条件。The lock emptying and dam flood relief would produce water level fluctuations in the lock downstream approach channel of the TGP,and thus flows generate to and fro motions.The unsteady flow would influence the safety navigation and mooring of ships.The flow characteristics and navigation conditions are introduccd in the paper.The results obtained by physical model test show that,besides the simultaneous emptying of locks of double line,in which case the value of water level fluctuation at the meusared point of ship lift chamber reaches 0.85m exceeding allowable value,the navigation flow conditions in the appoach channel basically satisfy the requirements of navigation and mooring of ships.Finally,the improvement measures are proposed.The measures are effective and may satisfy design requirements.
