Fully coupled dynamic simulations of uncompacted railway embankments under train loading

Abstract
Unlike modern earthworks, historic railway embankments were often end-tipped rather than compacted in layers and are susceptible to significant deformation and potentially failure. This study assesses the mechanical and hydraulic behaviour (deformation, stress migration and build-up of internal pore water pressure) of uncompacted railway embankments under different train loading conditions. A mixed finite element approach based on the complete solid displacement, fluid displacement and pore pressure (
