A note on determination of the preconsolidation pressure

Abstract

The preconsolidation pressure, σ 0y, is commonly interpreted by means of empirical observations (or graphical constructions) with respect to e–logσ 0 stress patterns (e = void ratio, and σ 0 = effective stress) exhibited in the conventional oedometer test. As with any empirical/graphical procedure, the resulting estimations are associated with subjective variability and thus yield inconsistent results among individuals. Recently, the mathematical translational technique was implemented by the authors, thereby promoting a subjective-free computational framework, denoted as the 3PRH framework, for interpretation of σ 0y with respect to four common graphical constructions (i.e., three semi-log ..
