某引水枢纽水工模型实验分析OA

A distorted overall fixed-bed(locally movable-bed)hydraulic model experiment was conducted to investigate the hydraulic and sediment-scouring characteristics of the sluice structures in a water diversion hub reinforcement project.The study examined water diversion capacity,discharge capacity,flow patterns,velocity distribution,and erosion-deposition morphology under typical discharge conditions.The results indicate that all gate operation schemes can meet the required discharge capacity under different operating conditions.By adding a submerged guide spur dike on the right bank upstream of the sluice,sediment deposition at the entrance of the artificial bend was effectively reduced,thereby improving the sediment flushing efficiency of the scouring sluice and mitigating sediment accumulation in front of the gates.The results provide a reference for sediment flushing and layout optimization in diversion hubs located in sediment-laden rivers.
