Description

The loading conditions of some thermal and mechanical isotropic tests are analysed based on analytical solutions which are applied to a transient step loading protocol. This allows to measure a drained and an undrained parameter and to back calculate the permeability of a low permeability material in one single test. A demonstration is given in a test on the Callovo-Oxfordian claystone. (authors)

Abstract (French)

On analyse les conditions de chargement d'essais isotropes thermomecaniques a partir de solutions analytiques qu'on applique a un protocole de chargement transitoire. Ceci permet la mesure de parametres draines et non-draines et de calculer par analyse inverse la permeabilite d'un materiau de faible permeabilite. Une application de cette methode est faite dans un essai sur l'argilite du Callovo-Oxfordien. (auteurs)
