摘要：Taking Lanqi SongHua River Bridge as an example, this paper has made an analysis of the dynamic character, wind-resistant stability and flutter instability are analyzed, especially the analysis of the flutter stability at maximum double cantilever stage during construction phase. This paper analyzes the dynamic characters of the FE model of the whole bridge through response spectrum method to reap the natural frequency, the vibration modes and other parameters, and then checks the flutter stability. The results show that the bridge is very safe. The analysis method provides bases and references for the wind-resistant of Lanqi SongHua River Bridge.
