Abstract

One of the important aspects of laboratory consolidation testing is the estimation of coefficient of consolidation (C-v) from which the rate of settlement can be predicted. Several researchers have proposed various graphical methods for obtaining estimates of C-v from laboratory oedometer tests. Literature suggests that the various graphical methods estimate different values for C-v for the same data and hence the only rational way to estimate the C-v value is based on the measured coefficient of volume compressibility (m(v)) and the coefficient of permeability (k). Guided by these considerations, an attempt has been made to establish the feasibilty of estimating C-v using stress-state-permeability relationships. Using these relationships, it is possible to estimate the coefficient of volume compressibility as well as the coefficient of permeability.
