Advances in Constructional Engineering

In the construction process of long-span steel structure, the force is complex, and the construction period is long, so it must be reasonable control. This paper mainly starts from the following aspects. Firstly, the present status and development trend of bridge engineering in our country are analyzed. Then, the paper expounds the tubular truss foundation, hoisting technique and quality inspection methods. Finally, the common problems in steel structure construction are discussed by combining theoretical calculations with practical data and corresponding suggestions are presented for reference. In this way, the control points in the construction of steel arch bridge with long span structure can be effectively formulated.
