| Outline of Final Research Achievements |
Floating-type ground improvement using soil cement columns, sand compaction pile,granulated blast furnace slag and so on can be very effective for the treatment of deep soft soil layers. This research project mainly has conducted as below;1)The interface shear mechanism between soft clay and construction material in the consolidation process has been clarified. 2)Stress distribution and settlement behaviour of floating type improved ground using sand compaction pile and GBFS were investigated. In particular, the influence of changing stiffness and permeability of geo-materials with elapsed time on settlement behaviour were indicated.
