摘　　要：新建红江闸由原址两座拦河水闸合建而成,工程所在河段河势、水流条件等较为复杂,对水闸的泄流能力、水流流态、消能防冲等设计不利,需开展水工模型试验,研究水闸泄流水力特性,解决存在的水力学问题。试验结果显示,原设计水闸存在两侧闸孔进闸流态不良、泄流能力不足,闸后消力池消能不足、海漫跌水严重等问题,试验对闸室两侧进水导墙、消力池等进行优化后,有效改善了过闸流态,提升了闸后消能效果和泄流能力,确保了水闸的泄流水力条件满足设计要求。研究成果已应用于工程并达到预期目标,可为同类工程设计和建设提供参考。The newly constructed Hongjiang Sluice was built by combining two existing river barrages at the original site.The river regime and flow condition of the reach where the project is located are complicated.Therefore,hydraulic model test were conducted to study the flow capacity,flow characteristics,and energy dissipation measures of the sluice,aiming to address hydraulic issues.The test results show that the original design of the sluice had poor flow conditions at the inlet of both sluice openings,inadequate discharge capacity,insufficient energy dissipation in the downstream energy dissipation pool,and significant sea water level fluctuations.After optimizing the design of the inlet guide walls and energy dissipation pool on both sides of the sluice,the flow conditions through the sluice were effectively improved,enhancing energy dissipation and discharge capacity.These modifications ensure that the sluice meets the design requirements for hydraulic conditions.The research findings have been successfully applied to the project,achieving the expected goals and providing valuable references for the design and construction of similar projects.
