Example Embodiment
[0034] See Figure 14 The implementation steps of the reinforcement structure of the present invention are as follows.
[0035] 1. Collect the structural parameters of the single cable plane cable-stayed bridge to be reinforced
[0036] See Figure 1 ~ Figure 5 The single-cable-plane cable-stayed bridge to be reinforced in this embodiment is a single-tower, single-cable-plane cable-stayed bridge, and the cable 19 on both sides of the bridge tower 3 is radially stayed between the bridge tower 3 and the main beam 1. ; Tower, pier, beam consolidation, its structural parameters are as follows: the span combination is (139+106)m, the tower height is 69m, the main beam 1 adopts a single box three-chamber box section, and the top plate width of the main beam 1 (ie, the bridge deck Width) 33.5m, bottom width 4.5m, main beam height 3.5m; bridge tower 3 and main beam 1 are constructed with C55 concrete.
