The invention discloses a partial cable-stayed bridge of a
fish bone beam structure. The partial cable-stayed bridge of the
fish bone beam structure comprises a main beam, a plurality of bridge towers and stayed cables, wherein anchoring ends or
saddle areas of the bridge towers are arranged on the main beam, the stayed cables are arranged between the main beams and the bridge towers, part of stayed cables further comprise multiple vertical walls corresponding to the bridge towers one to one, the vertical walls are
fish bone walls, the main beam is an equal-altitude box type bridge panel, columns of the bridge towers are embedded in the corresponding fish bone walls, and the tops of the columns of the bridge towers extend out of the fish bone walls. One end of each stayed cable is tensioned and anchored on the main beam, and the other ends of the stayed cables are anchored at the tops of the bridge towers or continuously pass through the
saddle areas. The partial cable-stayed bridge of the fish bone beam structure has all the advantages of a traditional cable-stayed bridge. The
structural rigidity of a bridge body is high, the stress of the bridge towers is more reasonable, the fish bone walls have the function of the bridge towers, the section is larger, and the bending performance is better.
