Embankment is a man-made structure. Unlike natural ground that has been formed over a long period of time, man-made structure is constructed in a short period of time. Generally, its strength and toughness are weaker than natural ground. Therefore, it is needed to apply enough compaction to the soil or/and apply a soil improvement to construct the embankment, which has enough strength and toughness.
In this section, ground improvement related technologies are described here.
