In embanking on peaty soft ground, the cost of maintenance is rising to repair long-term settlement or liquefaction occurring during earthquakes. To lower life cycle costs, research on rational countermeasure work methods or maintenance methods is performed under field conditions.

In cold snowy regions, problems which occur are quality management of embankments constructed during the winter and damage to civil engineering structures caused by frost heaving. Fact finding surveys and trial constructions are performed in the field to research construction technologies in cold environments.

Behavior during earthquakes of problematic soil as peat or volcanic ash soil will e clarified, and research conducted on earthquake resistance performance evaluations and reinforcement technologies for pile foundations constructed in problematic ground.
