Entry: Unconsolidated undrained triaxial test

URI: https://data.geoscience.fr/ncl/Proc/113

The unconsolidated undrained triaxial test (UU) aims to the determination of undrained shear strength under compression loading . The cylindrical specimen, which can comprise undisturbed, re-compacted, remoulded or reconstituted soil, is subjected to an isotropic stress under undrained conditions and thereafter is sheared under undrained conditions. The test allows the determination of shear strength and stress-strain relationships in terms of total stresses.

fr L'essai triaxial non consolidé non drainé (UU) a pour objectif la détermination en laboratoire de la résistance au cisaillement de sols non drainés en conditions de chargement par compression. L’éprouvette cylindrique, pouvant être constituée de sol non remanié, recompacté, remanié ou reconstitué, est soumise à une contrainte isotrope sans drainage et est ensuite cisaillée sans drainage. L’essai permet de déterminer la résistance au cisaillement et les relations contrainte-déformation en termes de contraintes totales.
