ABSTRACT: The increase in induced seismicity in the Fox Creek AB area has triggered the interest in site amplification for sites characterized by shallow rock. A new methodology to characterize the thin soil sites amplification is presented in this paper and is based on the characterization of the linear (initial) site fundamental period of vibration. The methodology is applicable to sites where soil having shear wave velocities smaller than 300 m/s overlay soft rock characterized by shear wave velocities between 360 and 760 m/s, typical of site C conditions. Amplification functions for hazard studies and foundation factors for engineering applications are developed and proposed to characterize the surface ground motion.

RÉSUMÉ: des sites caractérisés par des roches peu profondes. Une nouvelle méthodologie pour caractériser l'amplification de sites de sol minces est présentée dans cet article et est basée sur la caractérisation de la période de vibration fondamentale du site linéaire (initial). La méthodologie est applicable aux sites où le sol ayant une vitesse d'onde de cisaillement inférieure à 300 m / s recouvre une roche tendre recouverte de vitesses d'onde de cisaillement comprises entre 360 et 760 m / s, caractéristiques des conditions du site C. Des fonctions d'amplification pour les études de risque et des facteurs de base pour les applications d'ingénierie sont développées et proposées pour caractériser le mouvement du sol en surface.
