Rheological influences on the consolidation process of soils
Consolidation of soils is a complex hydrodynamic process; water is squeezed from the pores between the soil particles by the imposed loading. Shear strains are produced in the soil as the sample deforms and the rate of strain is associated with the escape of pore-water. The original Theory of Consolidation proposed by Terzaghi (1925) considered that the plastic resistance could be ignored as it was so small; in this way, a linear partial differential equation was developed to provide a time-settlement relationship for clays based entirely on the escape of pore-water.
