| Zusammenfassung: | The utility model relates to the technical field of bridge engineering, in particular to a steel box-concrete composite beam cantilever supporting structure which comprises a main beam web and a main beam top plate, a first cantilever stiffening plate is welded on the outer side of a right angle formed by the main beam web and the main beam top plate, and a second cantilever stiffening plate is welded on the outer side of the first cantilever stiffening plate. A cantilever top plate is welded to the top of the second cantilever stiffening plate, the cantilever top plate is welded to the main beam top plate, plug plates are welded to the outer side of the second cantilever stiffening plate and the outer side of the cantilever top plate, and the first cantilever stiffening plate, the second cantilever stiffening plate, the cantilever top plate and the plug plates jointly form a cantilever supporting structure. A cast-in-place concrete bridge deck is poured on the cantilever supporting structure; the cantilever |
