摘　　要：汛期三峡水库上游水位在150 m以下时,受船闸闸室充水运行的影响,与升船机共用的上游引航道水位短时变幅将明显增大,严重时会危及升船机的运行安全。通过收集三峡船闸运行数据和升船机上游引航道水位数据并展开分析,研究了船闸双线四级运行时二闸室取水对升船机上游引航道水位变化的影响。研究结果表明:在三峡水库出入库流量和船闸单次取水量不变的情况下,双线船闸二闸室取水在升船机上游引航道内引发的周期性往复流是导致水位短时大幅变化的主要因素,并就此提出了可行的应对策略。研究成果可为三峡升船机汛期安全运行提供指导。When the upstream water level of the Three Gorges Reservoir is below 150 m in flood season,the short-term variation of water level in the upstream approach channel shared with the ship lift will increase significantly due to the water filling operation of the lock chamber,which will seriously endanger the operation safety of the ship lift.Through the collection and analysis of the operation data of the Three Gorges ship lock and the water level data in the upstream approach channel of the ship lift,the influence of the water intake by the second lock chamber on the water level change in the upstream approach channel of the ship lift was studied.The results showed that under the condition that the inflow and outflow of the Three Gorges Reservoir and the single intake volumeby the ship lock were constant,the water intake by second lock chamber induced periodic reciprocating flow in the upstream approach channel of the ship lift,which caused short-term and large-scale changes of water level,and then feasible countermeasures were put forward.The research results can provide guidance for safe operation of Three Gorges ship lift in flood season.
