N2 - There have been various methods for characterizing consolidation behavior of clays with application of dissipation results from piezocone penetration tests (PCPT). Little attention however has been given to the evaluation of long-term compressibility that is represented by the compression index. It is primarily because no measurement of volume change is made during PCPT dissipation tests. In this study, a methodology for the estimation of long-term compressibility using PCPT dissipation results is presented. The coupled relationship of time-stress-volume change during consolidation is introduced into the investigation. Several case examples are selected and adopted to compare measured and predicted compression indices.
