Railway Embankment

With increasing train speed and wheel axle load, severe vibrations can occur in a ballasted trackbed, thereby accelerating the degradation of the ballast particles and ultimately causing excessive settlement. To gain insights into the long-term trackbed behavior and the ballast degradation evolution, a full-scale ballasted track experiment with eight sleepers was designed and tested on a validated physical model test platform (ZJU-iHSRT).

Presented at the Discrete Methods in Geotechnical Engineering for Transport Workshop held at the University of Edinburgh.

With the rapid development of high-speed railway over the world in recent years, more and more researchers are focused on the strength, stiffness and stability of the embankment. It’s more and more popular to use the discrete element method (DEM) to study cemented granular materials (e.g. rocks and concrete).
