Research on Flow Regime Hydraulics of Sluice-Passing Flows in Reconstruction Design of Large Sluice in Meandering River Channels
Large sluices in meandering river channels have large sluice-passing flow rates and turbulent flow regimes during floods,and downstream energy dissipaters of the sluice cannot be easily repaired once they are damaged by erosion.Taking the reconstruction of the Jimei Sluice as a research project,this...

| description | Large sluices in meandering river channels have large sluice-passing flow rates and turbulent flow regimes during floods,and downstream energy dissipaters of the sluice cannot be easily repaired once they are damaged by erosion.Taking the reconstruction of the Jimei Sluice as a research project,this paper tries to solve the problem that how to make the reconstructed sluice avoid the large scour pit that has a size of 50 000 m<sup>2</sup> and a maximum depth of 23 m and is formed by the erosion of current downstream stilling pools.In addition,the paper uses the technical route of changing the layout of the sluice opening and the angle between the sluice axis and the river channel centerline and establishes a two-dimensional hydrodynamic mathematical model to analyze the water level,sluice-passing flow regimes,and erosion.The results of the comparison find that the angle between the sluice axis and the river channel centerline is 88° (rotating counterclockwise by 2°),and the full-depth sluice scheme is suitable.The research ideas and methods can provide a reference for similar projects. |
