EXPERIMENTAL RESEARCH ON THE EFFECTS OF STRESS RELAXATION AND THE DETERMINATION OF MODULUS IN LOW STRAIN STATES

ESTUDIO EXPERIMENTAL SOBRE EL EFECTO DE LA RELAJACION DE TENSIONES Y LA DETERMINACION DE MODULOS A PEQUENAS DEFORMACIONES

A triaxial test program has been carried out on samples made with a lightly cohesive material of little expansion. The samples were modified in fixed conditions. The in situ soil state has been simulated and later, these and "perfect" samples with and without reconsolidation were tested. A comparison of results was made using the deformation modulus at low strains. By simple extrapolation, the original deformation modulus was estimated, making the necessary corrections in order to filter the equipment deformation. The accuracy of these results and of those from the usual methods of measuring modulus corresponding to a fraction of the ultimate load have been evaluated. Quantitative conclusions on the alterability of the laboratory results have been presented. (TRRL)
