Particularly, in urban bridge reconstruction and expansion projects, the requirements of existing bridges, pipelines, underbridge traffic requirements and municipal facilities are considered, the construction cost is saved, and the construction period and the influence of noise are reduced. Therefore, when bridge engineering design is carried out, a large cantilever bent cap structure is often adopted, the stress requirement of an upper structure can be met, and the driving space under a bridge can be enlarged.
