Abstract
The finite difference analysis of one-dimensional consolidation of clays, exhibiting large amounts of secondary compression during primary consolidation, provide fairly good predictions of the consolidation-time curve for oedometer specimens with different heights. Some parameters including the initial rate of secondary compression defined by primary consolidation in this analysis have been assumed to avoid experimental difficulty. The trial and error calculation procedure was therefore used where the calculated consolidation-time curves fit the observed ones. Finally, it is emphasized that the assumption for unknown secondary compression behaviors during primary consolidation has a predominant influence on the consolidation-time curve.
