Abstract

A double-track bridge consists of deck continuous steel-truss beam structure. Because there are 151.5m cantilever erection cases in the construction process of 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 steel-truss bridge. In order to simulate the contact problem of the piers and the steel truss beam, a new mechanical method is developed to simulate the non-linear contact of the pier and beam system in cantilever erection process. The mechanical model is combined with finite element method software. Then the iterative trial calculation and feedback adjustment operation mechanism are used in the finite element analyses of the whole erection process of steel truss bridge. Thus the reaction forces of latticed super high pier and its stress variation under different environmental temperature conditions in each construction stage are obtained. Based on accurate analysis of the stress status of the super-high piers subjected to the steel truss beam bridge, the reasonable suggestions are proposed for the construction of the steel truss beam and the piers, providing a simple analysis method for the construction calculation of the latticed super high pier.
