The article addresses the difficulty of controlling the installation accuracy of steel structures in the secondary design of the curtain wall of an irregular hyperbolic cable-stayed bridge without back cables. The "Optimized View 3D Laser Scanning" method is proposed,assisted by BIM technology,to perform reverse modeling and secondary design on the main and secondary keels and curtain wall structures of the irregular hyperbolic cable-stayed bridge without back cables,meeting the installation requirements of the irregu-lar hyperbolic keels and aluminum curtain wall. This study effectively ensures the accurate positioning and installation of complex bridge components,achieves good implementation results,and can provide reference for similar projects.
