One-dimensional response of peaty soils subjected to a wide range of oedometric conditions

Abstract

This paper describes a comprehensive set of experimental data concerning the one-dimensional, time-dependent behaviour of organic clays and peats. The experimental analyses concerned three different peaty soils (either undisturbed or remoulded) with fairly different index properties (the organic content ranged between 20% and 70%) that were submitted to various kinds of one-dimensional consolidation tests. The experimental data confirm that peats and organic clays have many aspects of their delayed behaviour in common. The main outcome of this work is a good-quality, comprehensive and meaningful set of data for use in developing and calibrating constitutive models for simulating the delayed response of soils, with an emphasis on organic clays and peats.
