| 中文摘要: |
| 峡江水利枢纽工程是目前为止江西省最大的水利枢纽工程。工程泄水闸采用弧形工作闸门+液压启闭机的布置方案，孔口尺寸大且泄流工况复杂。论文首先对弧形工作闸门运行过程中可能存在流激振动和侧向失稳等问题进行分析，并从设计角度提出了解决方案。在此基础上建立水力学模型，模拟分析了不同工况下闸门运行情况，为闸门安全运行提供了理论基础。工程自2016年建成至今已运行5年，泄水闸经多次开启泄洪，未出现任何险情。此研究成果可为大型弧形工作闸门的设计提供一定借鉴与参考。 |

| The Xiajiang hydro-junction project is the largest one of the hydro-junction projects in Jiangxi province so far.The sluice gate adopts the layout scheme of radial gate and hydraulic hoist.The orifice of sluice gate is large and the discharge condition of sluice gate is complex.This paper first analyzes the problems such as flow induced vibration and lateral buckling that may exist in the operation of radial gate,and the solutions are proposed from the design perspective.On this basis,the hydraulics model which simulates and analyzes the gate operation under different working conditions are established,which provides a theoretical basis for the safe operation of gate.The project has been in operation for 5 years since it was completed in 2016.The sluice gate has been opened many times for flood discharge without any danger.The research results of this paper can provide a reference for the design of large radial gate. |
