| 中文摘要: |
| 针对麻石船闸改建工程闸室规模大、工作水头高、水力指标要求高等问题，通过建立比尺为1:25的整体水工物理模型，对船闸输水过程水力特性、船舶停泊条件、输水廊道压力特性、进出水口及引航道水流条件等展开研究。结果表明：通过在明沟内增设消力槛、增大廊道突扩体升坎转弯半径、增加进水口面积以及降低进水口高程等优化措施，在推荐的阀门运行方式下，各项水力指标均满足规范及设计要求，研究成果可为类似工程提供参考。 |
| 英文摘要: |
| In addressing the challenges posed by the reconstruction of the Mashi ship lock,including a large lock chamber,high water head,and stringent hydraulic requirements,a physical model with a scale of 1:25 is established.The hydraulic characteristics of the water filling process,berthing conditions of the ships,pressure characteristics in the water transfer corridor,and flow conditions in the inlet/outlet and approach channel are investigated.The results show that through the implementation of optimization measures such as incorporating energy dissipating blocks in the open ditch,enlarging the turning radius of the corridor protruding body rising cans,increasing the inlet area,and decreasing the inlet elevation,all hydraulic indicators meet the specified standards and design requirements under the recommended valve opening mode.The research results can provide reference for similar engineering projects. |
