| Outline of Final Research Achievements |
When embankments are constructed on soft ground, including peat/clay, large residual settlement due to long-term settlement are often observed after the entry into service, and maintenance and repair work should be carried out repeatedly. This study proposed a countermeasure policy against long-term settlement of soft ground due to embankment loading with the aim of transferring the Japanese advanced technology to foreign countries which are also suffered from soft ground. The new numerical method could be effective tool for improving prediction accuracy for the long-term settlement, and also quantitatively evaluating the ground improvement effect of vertical drains/vacuum consolidation, considering ground conditions, construction costs and construction period.
