ABSTRACT: Previously, a miniature cone penetration test (MCPT) was developed at Western University to recreate in-situ CPT measurements at a smaller scale in a laboratory setting. In this study, improvements have been made to the MCPT setup which include the ability to measure shear wave velocity (VS) of the sample as well as initiate anisotropic consolidation which permits KO conditions to be applied to the sample. Laboratory testing using the MCPT at Western University is performed with sands found along the Fraser River located throughout Greater Vancouver, British Columbia. Empirical correlations between CPT tip and sleeve frictional resistances and shear wave velocity are established based on results from the MCPT tests as well as in-situ seismic CPT tests. Specific correlations for normalizing CPT tip resistance and VS are also developed for the Fraser River sand.

RÉSUMÉ: Auparavant, un test de pénétration de cône miniature (MCPT) a été développé à pour recréer des paramètres venant de CPT in-situ à une échelle plus petite dans un milieu de laboratoire. Dans cette étude, des améliorations ont été apportées à la configuration MCPT, qui comprend la capacité de mesurer la vitesse des ondes de cisaillement (VS consolidation anisotrope qui permet d'appliquer les conditions KO à l'échantillon. Les tests de MCPT à sont effectués avec des sables trouvés le long du fleuve Fraser situé dans le Grand Vancouver, en Colombie-Britannique. Les corrélations empiriques entre les résistances à la la vitesse des ondes de cisaillement sont établies en fonction des résultats des tests MCPT. Des corrélations spécifiques pour la normalisation de la résistance à la pointe du cône et les mesures VS sont également développées pour le sable du fleuve Fraser.
