Abstract:The Bandao Bridge is located in the central area of Danshui, Huiyang District, Huizhou City, Guangdong Province, and is a key bridge project in Huizhou City, Guangdong Province. The design conception of the bridge is novel and beautiful, and its structure type is reasonable and unique. Focusing on the design concept and structural characteristics of the Bandao Bridge, through the reasonable and refined design of the structure, this project conducts a reasonable and refined design of the structure, a series of means such as computer simulation analysis, bridge BIM technology, and three-dimensional spatial torsion no-thrust steel arch bridge construction and monitoring are comprehensively adopted to summarize the design key and innovative technology of the three-dimensional spatial torsion no-thrust steel arch bridge, which solves the key and difficult problems of bridge construction brought about by the innovation of bridge scheme, and can provide some reference for the design of similar landscape bridges.
