摘要：
High-velocity flow induced structure vibration and flood discharging energy dissipation in high arch dam are two main problems in hydropower station construction of China. This paper systematically introduces the research findings of authors from several facets such as hydrodynamic load character that can cause high arch dam to vibrate, the analytic method of flow-induced vibration and the hydroelastic simulation. The analytic method of vibration response of high arch dam by flood discharge flow was verified by tests of high arch dam hydroelastic models for Ertan, Xiaowan, Goupitan and Xiloudu hydropower station. It was also verified by prototype observation of flood discharge flow induced vibration of Ertan arch dam, both of which shows a good agreement.
