This report describes the deformation processes of the soft-ground embankment following the simulated seismic motion and the effect of the composite ground improvement technique to prevent deformation of the embankment and its surrounding foundation. This preliminary study was conducted with the aim of making recommendations for soft-ground embankment design resistant to earthquakes. Thought the result of the dynamic centrifuge model tests, we verified that the gravel foundation was effective in significantly reducing a settlement of the embankment crown and a deformation of the surrounding ground when subjected to simulated level-2 seismic motion.
