Abstract
En 中文
The lifting method of lattice girders in the construction of concrete-filled steel tube (CFST) arch bridges has always been a critical challenge in engineering practice. The construction process typically faces a series of technical difficulties, including limited lifting space, complex hoisting conditions, and intricate installation procedures. To address these challenges, this paper designs a novel crane capable of traveling along arch ribs and develops a corresponding lattice girder installation process. First, finite element analysis is conducted to comprehensively verify the structural stiffness and stability of the arch crane under extreme loading conditions. Second, a mechanical performance evaluation of critical load-bearing components of the bridge during construction is performed to ensure that the proposed method does not adversely affect the long-term serviceability of the structure. Finally, through an engineering application on a CFST arch bridge, the proposed method is validated in terms of construction efficiency, economic feasibility, and operational safety, demonstrating its practical applicability.
