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 distri-bution 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.
