Modified Terzaghi consolidation curves with effective stress-dependent coefficient of consolidation Available to Purchase

One of the assumptions of the standard consolidation theory used in soil mechanics is that the coefficient of consolidation is a material property that remains constant during the consolidation process. This note demonstrates numerically the effect on the consolidation rate of a coefficient of consolidation that changes with increasing effective stress. The letter proposes a set of dimensionless consolidation curves when the coefficient of consolidation is changing linearly over the incremental effective stress generating the consolidation.
