摘　　要：为了解决四方井水库溢洪道直线型进水渠导墙内水流流态紊乱,泄流能力不满足设计要求,同时当设计及以上洪水下泄时,消力池尺寸不足,消能不充分的问题,采用1∶50水工模型试验对溢洪道进水渠导墙型式和消力池尺寸进行了优化研究,分析了进水渠内水流流态、流速分布、泄流能力及消力池消能效果。结果表明:采用“直线+圆弧”的进水渠导墙型式,可有效改善进水渠内水流流态、流速分布,显著提高溢洪道泄流能力;增大消力池尺寸后,消力池消能率提升了6%~9%,出池水流更加平稳。研究成果可为类似工程溢洪道设计提供参考。In order to solve the water flow disorder in the spillway straight line inlet channel guide wall of Sifangjing water conservancy project, the discharge capacity does not meet the design requirements, and the size of the stilling pool is insufficient and the energy dissipation is insufficient when the current discharge design and above floods, we used the method of 1∶50 hydraulic model test, the type of guide wall and the size of stilling basin of spillway inlet channel were optimized, and the flow pattern, velocity distribution, discharge capacity and the efficiency of stilling pool in inlet channel were analyzed.The results showed that the guide wall type of straight line + arc could effectively improve the flow pattern and velocity distribution in the intake channel, and significantly improved the discharge capacity of the spillway.After increasing the size of the stilling pool, the energy dissipation rate of the stilling pool was increased by 6% to 9%,and the flow out of the pool was more stable.The research results can provide a reference for similar projects.
