摘要：To study the vortex induced vibration and flutter stability of streamlined box girder and the relevant anti-vibration measures, a large-scale segment model, which has a scale ratio of 1:40, of a large-span steel box girder suspension bridge was tested in a wind tunnel. In the test, some measures, such as changing the position of track of the overhaul vehicle and adding a central stabilizer, were taken to check the anti-vibration effect. The test results show that: when the central stabilizer is added, the flutter suppression effect is remarkable, and there is no obvious vortex anti-vibration effect; when the track of the overhaul vehicle is located in the middle of the main girder oblique web plate, suppression for vortex induced vibration is obvious, as for flutter, there is no inhibition effect, but excitation effect; when the track of the overhaul vehicle is located in the middle of the main girder oblique web plate and the central stabilizer is added at the bottom of the girder, the flutter and vortex induced vibration stability are effectively improved.
