Radial consolidation of a phase-change soil

Abstract

An overconsolidated sensitive clay has been represented by a one-dimensional compressional model in which the clay structure is rigid both below and above the maximum past effective stress and collapses at this stress from a higher void ratio to a lower value. This model is incorporated in several different geometries to describe the behaviour of the sensitive clay under applied stress. These cases include radial compression of a cylinder and a sphere, and expansion of a cylindrical cavity in an infinite region. Solutions are given for displacements and pore pressures.
