Session: In Situ Testing

ABSTRACT: North LRT expansion. The investigation included a series of in-situ testholes including a number of seismic CPTu holes and a pre-bored pressuremeter hole. The strength and deformation parameters obtained from the current investigation were then compared to the findings of a number of historical investigations associated with previous LRT extensions as well as several heavy civil projects located throughout the City of Edmonton.

RÉSUMÉ: -situ dont quelques essais de pénétration au cône sismique CPTu et un essai au pressiomètre préforé. Les paramètres de résistance et de déformation obtenus dans cette étude sont comparés aux résultats de plusieurs études antérieures concernant des expansions passées du LRT ainsi que plusieurs grands projets de génie civil réalisés à travers la ville
