Time-Dependent Deformation of Consolidation in Clay

Abstract

Results of theoretical analyses and series of experiments on the limitation of the time and magnitude of the secondary consolidation deformation in clay are presented. Characters of quasi-overconsolidation brought in secondary consolidation, relations between OCR and consolidated pressure are discussed. Secondary consolidation deformation develops with time, and the variability of the ratio of secondary consolidation deformation to one-day’s one (ε00-ε1)/ε1, with the pressure are finally presented.
