f Evolution of structural and physical parameters of clays under experimental compaction

In order to provide a better understanding of sedimentary basin development, it is very important to describe correctly the evolution of the various physical, mechanical and hydraulic properties of clayey rocks as a function of burial depth. As a contribution to this field, we are developing a program of experimental studies on reworked clay samples compacted under various load pressures in oedometric conditions. The initial study presented here is on a very simple material which can be used as an ideal case of compaction. Their evolution under compaction is then described with microscopic and macroscopic measurements.
