MECHANICAL BEHAVIOUR OF A NATURAL SOFT CLAY

摘要: The results of an experimental study on the mechanical behaviour natural soft clay found at Pisa are discussed. Triaxial and true triaxial stress path—controlled tests were carried out, in which soil was subjected to a variety drained paths, each starting from situ stresses. stress—strain observed be substantially non—linear very beginning loading process. interpreted using concepts hardening plasticity. influence damage produced microstructure during is evaluated through normalization technique. A comparison between reconstituted also presented. show strength anisotropy. In both tests, stiffness depend strongly direction path. Dans cet expose, nous presentons les resultats d'une etude experimentale sur le comportement...
