摘　　要：针对木京34 m宽船闸原方案下闸室泊稳条件较差的问题,采用数值模拟的方法,进行船闸输水系统灌水的数学模型试验,研究闸室不同消能工布置形式下的水流条件和停泊条件,揭示此类输水系统闸室输水特性。结果表明,在整个输水过程内,相较于采用1道消力槛消能工形式布置的原方案,采用“明沟+消力槛”的优化方案能够使闸室内水流流速更缓、水体表面紊动强度更弱、水面最大纵比降也更小,闸室泊稳条件得以改善。In response to the issue of poor mooring conditions in the chamber under the original plan of the Mujing 34-meter wide ship lock,we use numerical simulation method to conduct mathematical model tests on the water filling and emptying system,study the water flow conditions and mooring conditions in the ship lock chamber under various energy dissipater configurations,and reveal the water conveyance characteristics of such filling and emptying system in the chamber.The results indicate that throughout the entire water conveyance process,compared to the original design with a single dissipating sill,the optimized configuration of“open ditch+dissipating sill”results in slower water flow velocity,weaker turbulence intensity on the water surface,and a smaller longitudinal slope of water surface in the chamber.This optimization enhances the stability of mooring conditions in the chamber.
