| 中文摘要: |
| 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. |
