In view of the problem of insufficient reinforcement structural performance found in the construction technology of steel pipe arches for continuous beams of super large bridges spanning Changsha-Shenzhen highways, which results in a lower bearing capacity and deformation resistance of the reinforcement structure when dealing with complex stress situations of the bridge, as well as the deformation, cracks, and other issues experienced by the bridge during its long-term us, taking a certain highway bridge project as an example, the construction technology has been designed of continuous beam steel pipe arch for a super large bridge spanning Changsha-Shenzhen highways. Firstly, construction materials are prepared, construction equipment is debugged and the construction site is cleaned up; Secondly, the lifting point is determined and the lifting is completed by using a crane and the construction of the steel pipe arch is closed; Thirdly, concrete is prepared and poured according to the mixture ratio. After the construction is completed, post-maintenance and treatment are carried out. The application results of an engineering examples show that the horizontal and vertical displacement of the construction technology meet the design standards.
