三峡水利枢纽的双线5级连续船闸，是枢纽建成后长江水运大动脉的咽喉。船闸充水时，上游流速流态是保证航运畅通和船闸安全运行的重要因素。为此，中国三峡开发总公司要求对葛洲坝2号、3号船闸充水过程中，船闸上游的流速流态进行原型观测，为今后深入系统地进行原型观测与研究 The Three Gorges Project is a two-tier, five-level continuous ship lock that is the throat of the Yangtze River’s arterial artery after its completion. When the lock is filled with water, the upstream flow velocity is an important factor to ensure the smooth flow of the ship and the safe operation of the lock. To this end, China Three Gorges Development Corporation requires prototype observation of the flow velocity upstream of the ship lock in the process of water filling of No. 2 and No. 3 locks of Gezhouba Dam, so as to conduct in-depth and systematic prototype observation and research in the future
