In order to improve the spatial stiffness of the super long-span bridge structure, this paper introduces the three-dimensional cable network into the super long-span bridge design, and carries out the configuration research of the three-dimensional cable network bridge. The introduction of three-dimensional cable network design elements can improve the landscape of the super long-span bridge and the cultural connotation of the super long-span bridge. The three-dimensional cable network can greatly improve the lateral stiffness and torsional stiffness of the super long-span bridge, and enhance the wind stability of the super long-span bridge. The use of three-dimensional cable net technology measures is conducive to breaking through the technical bottleneck of super long-span bridges, and can provide reference for similar bridge design in the future.
