ABSTRACT: In this paper numerous quantitative parameters have been proposed for the characterization of the primary roughness of rock joint surface. Indeed, the primary roughness is the only component that prevails during large-slip faults of more than 50 m. The proposed parameters include: the degrees of apparent and real structural anisotropy of surface, the coefficients of real anisotropy and geometrical irregularity, the anisotropy function and the degree of waviness. The formulation of the parameters allows their application at both lab and field scales.

RÉSUMÉ: Dans cet article, de nombreux paramètres quantitatifs ont été proposés pour la caractérisation de la rugosité primaire des surfaces des joints rocheux. En effet, la rugosité primaire est la seule composante qui prévaut lors des grands glissements de failles pouvant dépasser 50 m. Les paramètres proposés sont: les degrés d'anisotropie structurale apparente et réelle de la surface, les coefficients d'anisotropie réelle et d'irrégularité géométrique, la fonction d'anisotropie et le degré d'ondularité. La formulation des paramètres permet leur application à la fois au laboratoire et à l'échelle du terrain.
