3D modelling of train‐track interaction at bridge transition
In bridge design Finite Element Method is the most commonly used tool for the calculation of stresses and strains in structures. The problem is more complex in case of high speed train infrastructure design due to the strict limitations of differential settlement in the transition zones. The railway transitions experience differential settlements due to differences in track system stiffness, track damping characteristics, foundation type, ballast settlement as a result of fouling and degradation, as well as fill and subgrade settlement. The problems associated with the transition zones require complex analysis. Aim of this study is to enhance our understanding of the dynamic behaviour of the bridge transition and its soil environment. The authors report the first results obtained by the investigation of a 3D numerical model of a bridge transition zone subject to dynamic loads of a structure embedded in soft soil environments using advanced constitutive model.
