The effectiveness of such load equivalence is usually testified by having similar results of key concerns of ballast bed, such as deformation or stiffness, while the consistency of particle scale characteristics under two loading patterns is rarely examined, which is insufficient to well-understand and use the load simplification. In this study, a previous laboratory model test of ballast bed under cyclic load is rebuilt using 3D discrete element method (DEM), which is validated by dynamic responses monitored by high-resolution sensors. 2023-04-18T04:10:15Z 2023-04-18T04:10:15Z 2023 Book https://link.springer.com/article/10.1007/s40534-023-00310-8 https://dlib.phenikaa-uni.edu.vn/handle/PNK/8031 en application/pdf Springer
