Configuration and Application of Three-Dimensional Space Cable Network Bridge

Abstract

To improve the spatial stiffness of a superlong-span bridge structure, this paper introduces the three-dimensional cable network to a superlong-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 superlong-span bridge and the cultural connotation of the superlong-span bridge. The three-dimensional cable network can greatly improve the lateral stiffness and torsional stiffness of the superlong-span bridge and enhance the wind stability of the superlong-span bridge. The use of three-dimensional cable net technology measures is conducive to breaking through the technical bottleneck of superlong-span bridges and can provide reference for similar bridge design in the future.
