Dynamic Stress of Subgrade Bed Layers Subjected to Train Vehicles with Large Axle Loads

The dynamic responses of subgrade bed layers are the key factors affecting the service performance of a heavy-haul railway. A 3D train-track-subgrade interaction finite element (FE) model was constructed using the ABAQUS code, where different vertical irregular track spectra were simulated by modify...
