Study on the practices for preconsolidation stress evaluation from oedometer tests

Abstract

The preconsolidation stress (pc') is determined from high-quality oedometer test results by a variety of interpretation methods. Sample quality in the database varies from very excellent to fair (i.e. class 1-2). Results show that the five methods applied give very similar pc' values when the samples are of good quality, with pc' varying up to 14% between the five methods.
