摘　　要：石花控制闸是引江补汉工程的控制枢纽,采用品字型双层闸门布置解决了引江补汉工程高水头、超长有压输水水力控制关键技术难题。为了探究石花控制闸品字型双层闸门水力控制技术,采用数值计算和水工模型试验的方法开展研究:①采用一维、三维耦合数学模型计算控制闸启闭引起的系统水力过渡过程,为工程设计提供边界条件;②采用物理模型试验分析控制闸体型的合理性。结果表明:系统沿线最大、最小压力均满足相关规程要求;控制闸内水流流态、压力分布等指标正常,控制闸体型合理。石花控制闸总体设计方案合理,布置方式和研究方法可为其他类似工程提供参考。Shihua sluice serves as the control hub for the Water Diversion Project from the Three Gorges Reservoir to the Hanjiang River.A double-layer gate layout is employed to address key technical challenges in hydraulic control such as high-head and long-pressurized water conveyance.Numerical calculations and hydraulic model tests were conducted to explore the hydraulic control technologies in the double-layer control gate.A one-dimensional and three-dimensional coupled mathematical model simulates the hydraulic transition process resulting from the opening and closing of the control gate,providing essential boundary conditions for engineering design.Physical model test analyzes the rationality of the control gate shape.Findings indicate that the maximum and minimum pressures throughout the system comply with relevant regulations.Parameters such as water flow patterns and pressure distribution are normal,and the shape configuration is appropriate.Overall,the design scheme for the Shihua sluice is effective.Its layout and our research methods offer reference for similar projects.
