摘要：

In this paper study findings of flow-induced vibration of gate in the emptying culvert of Tishengqiao power station are presented. At first stage structure's dynamic characteristics are investigated carefully using the experimental modal analysis technique, and entire structure modal information is obtained, In addition, flow pulsating pressure properties acting on the gate are investigated. Various physical values including vibration acceleration, dynamic displacement and dynamic stress caused by high velocity flow are studied. Finally gate structure's dynamic reliability is analyzed and safety operation principle are presented.
