The Evolution of Direct Simple Shear Testing: A Literature Review
Dan Bruton, David Randt
In the proceedings of: GeoVirtual 2020: 73rd Canadian Geotechnical ConferenceABSTRACT: Prior to Kenneth Roscoe’s work at Cambridge University, the only available shear testing device was the Direct Shear (DS) test, which had a significant limitation in that it did not permit rotation of the principal axes during shearing. In this test, the sample was forced to fail along a specified failure surface between the upper and lower parts of the shear box. In 1953, Roscoe improved the direct shear test with the addition of hinged walls. This test facilitated rotation of the principal axes, enabled simple shear, and did not force the soil to fail through a specified failure surface. Since then further advancements have been made in the evolution of shear testing. This paper provides a summary of the evolution from the 1800s to present day.
RÉSUMÉ: Avant les travaux de Kenneth Roscoe à l’Université de Cambridge, le seul appareil d’essai de cisaillement disponible était le Direct Shear (DS), un dispositif de cisaillement direct, qui présentait une limitation importante en ce qu’il ne permettait pas la rotation des axes principaux pendant le cisaillement. Ce dispositif forçait l’échantillon à se rompre le long d’une surface de rupture spécifiée entre les parties supérieure et inférieure de la boîte de cisaillement. En 1953, Roscoe a amélioré l’essai de cisaillement direct en ajoutant des murs articulés. Cette nouvelle méthode facilitait la rotation des axes principaux, permettait un cisaillement simple et ne forçait pas l’échantillon de sol à se rompre le long d’une surface de rupture spécifiée. Depuis lors, de nouveaux progrès ont été réalisés dans l’évolution des essais de cisaillement. Cet article résume l’évolution de ces essais des années 1800 à nos jours.
