The structure of Qiantang River Bridge on Hangzhou - Ningbo Expressway is a catenary continuous steel truss bridge with span combination of ( 73.4 + 122 + 4 × 240 + 122 + 73.4 ) m and total length of 1350.8 m. The main truss of the superstructure is constructed from both sides to the middle span by using the walking jacking method and the dragging jacking method, respectively, and finally the middle span is closed directly. In order to make the alignment and stress of the bridge reach the design goal, the construction control content of the bridge is determined based on the engineering characteristics and construction method of the steel truss girder of Qiantang River Bridge, and the finite element calculation results are also combined with as well. The construction control results show that during the whole jacking construction process, the stress state of the main truss linear and structure of the bridge is controlled within the specification limit, and the deviation from the theoretical value is small, and the construction monitoring target is achieved.
