摘　　要：三峡升船机布置在三峡枢纽左岸,北侧与三峡船闸相邻,右侧与三峡电厂毗邻。与国外升船机布置在人工运河上相比,三峡升船机布置在天然航道上,且地处三峡船闸和三峡电厂中间。受枢纽防洪调度、发电调度及三峡船闸运行的影响,不同时期的水情变化对三峡升船机的运行会产生不同程度的影响。对三峡升船机全年不同时期的上下游水情特点进行分析,并采用数据统计分析的方法分析水位变化对上下闸首工作门门位调整的影响及水位波动导致的水位变幅超限及调整船厢水深次数增加的规律。最后,从运行管理的角度提出加强与调度部门的联系、加强水位数据的运用分析及进一步探索运行操作技巧3个运行应对建议,以期提高运行人员对水位变动的应对水平。The Three Gorges shiplift is arranged on the left bank of the Three Gorges project.The north side is adjacent to the Three Gorges ship lock and the right side is adjacent to the Three Gorges power plant.Compared with foreign shiplifts placed on artificial canals,the Three Gorges shiplifts are placed on natural waterways,and located between the Three Gorges ship lock and the Three Gorges power plant.Affected by the hub's flood control dispatch,power generation dispatch,and Three Gorges ship lock operation,the changes in water condition will have impacts on the operation of the Three Gorges shiplift.This paper analyzes the upstream and downstream water features of the Three Gorges shiplift at different times of the year.The method of data statistical analysis is used to quantitatively analyze the effect of water level changes on the adjustment of the working gate position of the upper and lower lock heads,as well as the law of water level fluctuations exceeding the limit and increasing the number of times of adjusting the water depth of the cabin.Finally,from the perspective of operation management,three operational response suggestions are put forward to tighten the contact with the dispatching department,strengthen the analysis of the use of water level data and further explore operational skills,with a view to improving the level of response to changes in water levels of the operating personnel.
