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 (𝜓) controls soil behaviour, it is the preferred index to estimate 𝐶𝑅𝑅. 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 𝐶𝑅𝑅.
RÉSUMÉ: L’approche critical state offre une méthodologie théoriquement solide pour évaluer le potentiel de liquéfaction de matériaux granulaires. Le state parameter (𝜓) est l’indice privilégié pour estimer 𝐶𝑅𝑅, puisque la valeur de 𝜓 contrôle le comportement d’un matériau. Dans la présente étude, des résultats de laboratoire publiés dans la littérature sont utilisés afin d’estimer 𝐶𝑅𝑅 en fonction de 𝜓. La base de données inclut des sables normalisés, des sables à sables silteux naturels ainsi que des résidus miniers. L’objectif principal est d’évaluer l’influence du pourcentage de fines sur 𝐶𝑅𝑅.
