Abstract

The main aim of this paper is to quantify the long-term behaviour of a high-speed transition zone between embankment and bridge capturing correctly the longitudinal and vertical variability of track properties with low computational costs. In order to do so, a methodology has been proposed consisting of three main modules (i.e. dynamic module, superposition module and settlement module) that are iteratively called until a stopping criteria is met. A FE model informs the dynamic module through receptance and cross-receptance curves and an additional FE model is used to pre-calculate the stress level under a unit load. In this paper, the composite track stiffness is calculated and the areas with highest dynamic loading rate are analysed in detail for the direction of travel towards the bridge. The model is then used to assess the role of the travelling speed in the short- and in the long-term track behaviour.
