Abstract: Redial gate is widely used in hydraulic structures. For many gates, owning the responsibility of water discharge control, strong vibration may occur in daily operation. More and more attention is paid on the flow-induced vibration, kinetic stability, the safety and reliability of the gate structure. In order to get the first-hand dynamic operation data, it is necessary to conduct systematic observation on flow induced vibration as well as the static and dynamic prototype observation of the radial gate of flood discharge and diversion tunnel in Fengman reconstruction project. By analysis and evaluation, reasonable operating rules for safe operation of the gate can be set, which would guide the future operation and management of the project and is of great engineering significance.
