Embodiment 1
[0085] like figure 1 A ribbon-shaped single-tower cable-stayed-rigid frame composite bridge is shown, including the lower support structure of the bridge, the main girder 4 located above the lower support structure of the bridge, which is arranged on the main girder 4 and gradually tilts backward from bottom to top The main tower 1 and two ribbon-shaped support structures located on the rear side of the main tower 1, the main tower 1 is arched, and the structures of the two ribbon-shaped support structures are the same and they are arranged symmetrically on the left and right sides of the main tower 1 On both sides, the two streamer-shaped support structures are fastened together with the main girder 4 and both are arranged along the longitudinal direction of the bridge. Between the main tower 1 and the main girder 4, a plurality of stay cables 5 are arranged, and the stay cables 5 are arranged from top to bottom and are all located at the front side of the main tower 1. Each ...
Embodiment 2
[0138] In this example, if Figure 9 As shown, the number of the single-tower cable-stayed ribbon-shaped combined force-bearing system is two, and the two single-tower cable-stayed ribbon-shaped combined force-bearing systems are arranged symmetrically.
[0139] During actual construction, according to specific needs, the number of the single-tower cable-stayed ribbon-shaped combined stress system is adjusted, and by increasing the single-tower cable-stayed ribbon-shaped combined stress system, the ribbon-shaped independent stress system of the construction is increased. Spanning capacity of tower cable-stayed-rigid frame composite bridge.
[0140] In this embodiment, the structures, connections and construction techniques of the remaining parts are the same as those in Embodiment 1.
