ABSTRACT: As the demand for deeper site exploration continues to increase because of heavier structural loads and larger more critical projects, the utilization of seismic piezocone testing (SCPTu) is clearly an optimal approach for geotechnical site characterization, since up to five separate readings (qt, fs, u2, t50, and VsVH) on soil behavior are procured during a single sounding. The advancement of such soundings can routinely achieve depths of 30 to 60 m. With specialized equipment and procedures, penetration depths of 100 to over 160 m are now possible.
RÉSUMÉ: L™exploration profonde de sites suscite un intérêt certain, et ce, plus particulièrement en raison de la demande grandissante pour des infrastructures de plus grandes tailles et pouvant supporter des charges de plus en plus importantes. L™utilisation du piézocône sismique stable (SCPTu) est définitivement l™une des techniques privilégiées pour la caractérisation des sites géotechniques. Son utilisation permet d™obtenir, lors d™un même sondage, cinq lectures séparés (qt, fs, u2, t50 et VsVH) sur le comportement du sol. L™avancement de telles techniques de sondage permet d™atteindre des profondeurs de pénétration de 30 à 60 mètres. Ces profondeurs peuvent même atteindre de 100 à 160 mètres avec un équipement spécialisé.
