| 中文摘要: |
| 输水系统是船闸的核心，其设计方案直接影响船闸通过能力，是船闸设计的关键参数。针对微山三线船闸输水规模较大、水力指标和输水效率要求较高的问题，通过比尺1:30的物理模型试验，对各工况及船闸输水系统布置方案下的水力特性、船舶泊稳条件及输水系统的消力设施等进行研究。结果表明，进水口取消进水格栅，采用消涡板，从技术和经济上优化了船闸设计；出水口消能工布置和下游引航道辅导航墙线型优化使得水流条件得到明显改善。优化方案输水系统布置在闸门开启方式下，各项水力指标均满足设计和规范要求，输水系统整体设计是合理可行的。 |

| The filling-emptying system,which is a key parameter in lock design is the core of a ship lock,and its design directly affects the lock's carrying capacity.In response to the large-scale filling-emptying,and high requirements for hydraulic indicators and conveyance efficiency of the Weishan third-line ship lock,the hydraulic characteristics,ship berthing stability conditions,and dissipation facilities of the filling-emptying system under various working conditions and layout of the filling-emptying system are studied by a physical model test with a scale of 1:30.The results indicate that the lock design is optimized technically and economically by removal of inlet grilles and the use of vortex plates at the inlet.The arrangement of energy dissipation work at the outlet and the optimization of the navigation wall shape for the downstream approach channel guidance significantly improves the water flow conditions.Under valve opening mode of optimized layout of the filling-emptying system,all hydraulic indexes can meet the requirements of the design and the codes,and the overall design of the filling-emptying system is reasonable and feasible. |
