Zusammenfassung:The invention provides a split box girder bridge vortex-induced vibration turbulent flow device which comprises a split box girder and turbulent flow units, and an array composed of a plurality of turbulent flow units is arranged at the slotting position of the split box girder. Each turbulent flow unit comprises a lattice, a vibration exciter and a plurality of elastic pieces; the turbulent flow units are arranged at the slotting positions of the split box girders, the spanwise vortex structures of vortexes at the slotting positions of the split box girders are destroyed, the vortex vibration damage of a large-span split box girder bridge can be effectively eliminated, and the vortex vibration damage of the large-span split box girder bridge can be effectively eliminated. The air flow can be preliminarily disturbed through an elastic piece in the turbulent flow unit when passing through the split box girder, the vibration exciter can be remotely controlled, the air flow erupted by the vibration exciter can b
