Summary

Assuring an appropriate maintenance of ballasted railway track is crucial to keep the safe rolling of increasing train traffic. The lateral resistance of the ballasted track must be kept above a critical level to avoid lateral buckling of the rails. Railway maintenance procedures of tamping and stabilisation have an impact on this resistance. The aim of this paper is to analyse this impact by using the numerical method called the discrete element method and more particularly its non-smooth contact dynamic approach. The effects of the maintenance procedures are presented in terms of compaction, settlement and lateral resistance and the correlation between them.
