Resum
Experimental results of triaxial tests performed on unsaturated soil samples of statically compacted Boom clay are presented. Boom clay samples we re subjected to radial stress paths at two different constant water contents: w= 15%, the as-compacted one, and w= 18%, achieved by vapour transfer technique from the as-compacted condition. The dependence of volumetric compliance on the stress ratio and on the water content is evidenced. The results of the experimental investigation are interpreted i...
