| 中文摘要: |
| 三峡升船机水位波动受电站调峰、船闸泄水等因素影响，变化非常复杂，下闸首水位变率可达0.9 m/h。三峡升船机运行期间，水位波动导致的停机故障占比约29%，经常影响升船机运行安全。通过收集升船机运行停机故障数据并展开分析，研究水位波动对升船机运行的影响，并从运行对接前期、船厢与闸首对接期间、开船厢门期间、船厢与航道连通期间4个阶段提出水位监测应对建议。在易受水位波动影响的敏感环节应提前做好水位趋势预判，掌握水位波动规律，及时采取相应措施避免三峡升船机发生停机故障。 |
| 英文摘要: |
| The fluctuation of the water level of the Three Gorges ship lift is influenced by the peak shaving of the power station，the discharge of the ship lock and other factors，and the change is very complicated，and the water level variability at the head of the lower sluice can reach 0.9 m/h.During the operation of the Three Gorges ship lift，the shutdown failure caused by water level fluctuation accounts for about 29%，which often affects the operation safety of the ship lift.In this paper，the influence of water level fluctuation on ship lift operation is studied by collecting and analyzing the fault data of ship lift operation and shutdown.Suggestions on water level monitoring are put forward from four stages，including the early stage of operation docking，the docking period between the chamber and lock head，the opening period of the chamber，and the period of chamber connecting channel.The trend of water level should be predicted in advance in the sensitive links that are easily affected by water level fluctuation，the law of water level fluctuation should be mastered，and the corresponding measures are taken timely to avoid shutdown failure of the Three Gorges ship lift. |
