WebObject Moved This document may be found here WebThis paper first presents a unique relationship between permeability and void ratio. This relationship is then used for deriving the governing differential equation of consolidation for normally consolidated soils where void ratio vs. logarithm of effective stress can be approximated by a straight line.

Web18 de mai. de 2024 · For normally consolidated clays c'=0. For overconsolidated clays, c' is not very large and is typically within the range of 0 to 500 psf. By dissipation of pore water pressure, i.e., consolidation, effective stress ( p' ) would increase and consequently soil shear strength would increase following the drained strength envelop shown in Figure 1.
