Steady-states modelling of railways : ballast behaviour and ballast wear
, 2018 Le développement récent du transport ferroviaire a conduit à une forte augmentation du trafic durant la dernière décennie, augmentation qui devrait sepoursuivre dans la décennie à venir avec les futurs développements de ce mode de transport. L'augmentation du trafic se traduit pour l'infrastructure par une augmentation des sollicitations subies par les

The influence of support conditions on short- and long-term track behaviour [PDF]
Railway track support conditions are known to deeply affect the dynamic performance of vehicle-track interaction, influencing the state of the track system both in the short and in the long term.

Determination of Substructure and Sub-ballast Layer Thickness of High-Speed Railway
Journal of Materials and Engineering StructuresThe thickness of trackbed layers plays a crucial role in distributing train loads to ensure that stresses on the sub-ballast and substructure remain within acceptable limits. Vietnam is currently studying the construction of a high-speed railway (HSR) on

Finite Element Method for Improving Soft Soil Underneath a Ballast Railway Track
Journal of Engineering and Sustainable Development, 2013 It is always recommended to improve the properties of the soft soil beneath the railway networks often in such cases to increase its ability in bearing different applied loads and to control the expected generated settlements.
