INTRODUCTION

The behaviour of a given soil depends on its state, defined

in terms of stresses and specific volume or water content,

and structure, which may be due to fabric and/or bonding.

Stiff sedimentary clays will have a structure resulting from

their deposition by sedimentation and in some cases from

post-depositional processes. An important effect of this
