Terzaghi’s consolidation theory assumes strain in soil due to applied overburden pressure is small, and permeability and thus the coefficient of consolidation (Cv) remain constant during consolidation. Although valid for soft soil consolidation, the Cv for hydraulically placed slurry materials with low solids content may change significantly during the consolidation process as the material transitions from a slurry to a solid. In this study, a spatial and temporal variable Cv was used to predict the time rate of consolidation of fine coal refuse placed in an impoundment as a slurry. The results suggest the variable …
