Large-span inclined arched bridge tower cable-stayed bridge
The invention discloses a large-span inclined arched bridge tower cable-stayed bridge which comprises a plurality of stay cables, large-span cable-stayed bridge inclined curved bridge towers, first foundations, second foundations and third foundations. The bridge towers are composed of upper cantilevers and bottom supports, and the upper cantilevers are inclined towards the midspan. The bottom supports comprise first supporting legs, second supporting legs and third supporting legs, and the first supporting legs, the second supporting legs and the third supporting legs are rigidly connected to the first foundations, the second foundations and the third foundations respectively. Transverse supporting beams are arranged between the first supporting legs and the second supporting legs. The top ends of the stay cables are longitudinally fixed to the side faces, towards the midspan, of third arches respectively, and the bottom ends of the stay cables are longitudinally fixed to the midspan of the bridge. Back cables are arranged on the backs of the bridge towers. The top ends of the back cables are fixed to the top ends of the upper cantilevers of the bridge towers, and the bottom ends of the back cables are fixed to the third supporting legs of the bridge towers. The height and cost of the cable-stayed bridge are effectively lowered, modeling is attractive, the overall structure is stable, and the requirement of a height limiting area is met.
