Publikováno v: Transportation Geotechnics. 6:84-96

When high speed trains travel close to the wave propagation velocity of the supporting track-ground system, large amplitude track deflections are generated. This has safety implications, and also results in a significant increase in track maintenance

Application of Coupled Train-Track Modelling of Critical Speeds for High-Speed Trains using Three-Dimensional Non-Linear Finite Elements

Publikováno v: International Journal of Railway Technology. 4:1-35

It is known that as trains traverse soft soils a critical point can be reached whereby the train speed will exceed the Rayleigh ground wave velocity leading to critical velocity issues. If track structures are present, such as stiffened embankments,
