Abstract

Floating-type ground improvement using soil cement columns, steel piles, and steel sheet piles can be very effective for the treatment of deep soft soil layers. The skin friction between soft clay and construction material is one of the significant parameters in soil-material interaction problems. However, the interface shear mechanism between soft clay and construction material in the consolidation process has not been clarified. In this study, first, ring shear tests were performed to evaluate the clay-material interface behavior under drained shear conditions using two types of soft clays. Second, as one of the soil-structure interaction problems, the correlation between the surface roughness of the soil cement column and the soft clay particle size was investigated for evaluating the interface shear strength.
