Entry: Rock - Direct shear testing along a rock joint - Normal surface joint, constant load testing

URI: https://data.geoscience.fr/ncl/Proc/138

The direct shear test is performed along a discontinuity present in a rock specimen. The sample is placed in the shear box such that the discontinuity is horizontal, it is then loaded vertically (normal stress) and sheared at a controlled deformation rate until it breaks.

fr L'essai de cisaillement direct rectiligne est réalisé le long d'une discontinuité présente dans une éprouvette de roche. L'échantillon est placé dans la boîte de cisaillement de manière à ce que le plan de discontinuité soit horizontal, il est alors chargé verticalement (contrainte normale) puis cisaillé à vitesse de déformation contrôlée, jusqu'à la rupture.
