Embodiment
[0021] Embodiment 1: Taking a single-tower cable-stayed bridge as an embodiment, figure 1 It is a schematic diagram (elevation view) of the main structure of the bridge of the present invention, and the cooperation system includes a bridge tower 1, side piers 2, main girder 3, asymmetric curved arch 4, stay cables 5 and inclined suspenders 6.
[0022] The stay cables 5 and the inclined suspenders 6 distributed along the longitudinal direction play the role of elastic support for the main girder 3 . Outside the area of the asymmetric curved arch 4, the two ends of the stay cables 5 are respectively anchored on the bridge tower 1 and the main girder 3; while in the area of the asymmetric curved arch 4, the oblique suspenders 6 are obliquely anchored to the asymmetric curved arch 4 On the arch rib, the oblique suspension rod 6 and the stay cable 5 are anchored at the same point on the arch rib of the asymmetric curved arch 4, and are located on the same straight line, and the...
