Normalization of Strength Characteristics of Remolded Ariake Marine Clays

Abstract

In this paper, the changes in the undrained shear strength in the consolidation, swelling, and recompression processes for remolded Ariake marine clays are investigated from the point of normalization of the strength characteristics of the clays. It was found that the strength characteristics in the consolidation, swelling, and recompression processes for remolded Ariake marine clays can be normalized using the generalized Hvorslev failure criterion and overconsolidation ratio, OCR, defined by Hvorslev. This normalization procedure embraces the usual one in which the overconsolidation ratio, OCR, is used, and can be applied to clays exhibiting a nonlinear relation between the shear strength and effective normal stress at failure in the normal consolidation process.
