| Abstract: | The spillway tunnel at Xiluodu Hydropower Station has the characteristics of large discharge and high flow velocity, for which the hydraulic characteristics of the emergency gate and the dynamic properties of gate structure during shutting down under hydrodynamic condition are directly related to the technical feasibility and the safety reliability of the spillway tunnel operation. The flow regime inside of the tunnel, the characteristics of hydrodynamic load, the hydrodynamic pressure feature at the gate slot and the vent air speed during the shutting of the gate is studied through model test, and then the reliability of the gate, the feature of the vent air speed and the pressure at the gate slot during the shutting of the gate are analyzed based on the test result concerned. |
