摘　　要：针对三峡升船机运行流程中部分机构运行时间较长、影响运行效率的问题,开展了升船机运行流程优化研究。通过统计分析和理论计算,指出上下游航道水位差小于一定范围时抽管道水步序会影响升船机运行效率。结合长期的运行管理经验,提出三峡升船机抽管道水流程优化方案,并进行安全性论证和效能分析。结果表明:现有条件下,流程优化后可每厢次节约升船机设备运行时间约70 s,极大提高升船机运行效率。In view of the long running time of some mechanisms in the operation process of the Three Gorges ship lift and its influence on the operation efficiency of the ship lift, we carry out research on optimizing the operation process of the ship lift. According to statistical analysis and theoretical calculation, when the water level difference between the upstream and downstream channel is smaller than a certain range, the pipeline water pumping sequence affects the operational efficiency of the ship lift. In light of long-term operation and management experience, we propose an optimization plan for the pipeline water pumping process of the Three Gorges ship lift and conduct safety argumentation and efficiency analysis. The results show that under the existing conditions, the operation time of the ship lift is saved by about 70 s per compartment after process optimization, which greatly improves the operational efficiency of the ship lift.
