Summary

The work, described in this paper, focuses on the impact of increasing moving load speed and the loading history on the initial state evolution of the railway platform soil. A numerical model of the railway track and the platform, which can take into account both dynamic loading and non-linear material behavior is used. According to the response obtained, it seems that increasing the moving load speed affects mostly the deviatoric response of the soil. It is also noted from the numerical simulations that pre-loading the track with a moving load at a low speed before applying nominal speed leads to volume reduction and an increase in confinement. These aspects can be related to platform compaction during track construction and give an insight into increasing the train speed after a track renewal.
