A double-track bridge is continuous steel-truss beam structure, which consists of 7 spans. Because there are 151.5m cantilever erection cases in the construction process of the steel-truss bridge from side pier to main pier, the two super-high piers with height of 110.9m and 133.5m are set at 81m distance from two side piers to shorten the cantilever erection length of the steel-truss bridge. In order to ensure the safety of construction, the whole mechanical models of the steel-truss bridge together with the super-high pier and bearing beam are established in this paper. In the whole erection process of the steel-truss bridge, the bearing beam connects the steel-truss bridge and the super high pier, which is the main bearing structure. Then, the finite element method (FEM) with three dimensional shell elements and body elements is used to analyse the stress and deformation status of the bearing beam during the construction of the continuous steel-truss girder. Based on the analytical results from FEM, the reinforcement schemes are proposed for the initial design of the bearing beam where the local buckling or insufficient strength will occur under dangerous working cases. The structural reinforcement strategy makes the bearing beam meet the safety requirements under the construction process. The results of the present paper can provide reference for pier top layout and reinforcement analysis of similar super-high piers.
