A CRITICAL REAPPRAISAL OF COMPRESSION INDEX EQUATIONS

It is revealed that the ratio of the void ratio e to the void ratio at the liquid limit e-l versus the net repulsive pressure r-a relation is more general and fundamental than the half-space distance d versus r-a relation. With the possibility of two modes of linearization of e/e-l versus the effective consolidation pressure p relation, two generalized compression index equations for normally consolidated saturated fine-grained soils have been derived. Most of the existing empirical compression index equations have been re-examined for their rationale and applicability by comparing them with the generalized compression index equations.
