ABSTRACT: The critical state approach proposes a theoretically-sound mechanistic framework which can be applied to liquefaction assessment in cohesionless soils. Because the value of the state parameter () controls soil behaviour, it is the preferred index to estimate . In this paper, available data from the literature are compiled and re-analyzed to derive soil-specific cyclic resistance curves. The database includes laboratory standard sands, natural clean to silty sands, and silty mine tailings. The objective of this work is to assess the influence of fines content on .

RÉSUMÉ: critical state offre une méthodologie théoriquement solide pour évaluer le potentiel de liquéfaction de matériaux granulaires. Le state parameter () , puisque la valeur de contrôle le ittérature sont utilisés estimer en fonction de . La base de données inclut des sables normalisés, des sables à sables silteux naturels u pourcentage de fines sur .
