Assessing the potential of internal instability and suffusion in embankment dams and their foundations / Chi Fai Wan in Journal of geotechnical and geoenvironmental engineering, Vol. 134 N°3 (Mars 2008) 

Public ISBD [article]  in Journal of geotechnical and geoenvironmental engineering > Vol. 134 N°3 (Mars 2008) . - pp. 401–407 Titre : Assessing the potential of internal instability and suffusion in embankment dams and their foundations Type de document : texte imprimé Auteurs : Chi Fai Wan, Auteur ; Robin Fell, Auteur Année de publication : 2008 Article en page(s) : pp. 401–407 Note générale : Geotechnical and geoenvironmental engineering Langues : Anglais (eng) Mots-clés : Soil  erosion  Dams  Embankment  Dam  foundations Résumé : Suffusion is the process by which finer soil particles are moved through constrictions between larger soil particles by seepage forces. Soils susceptible to suffusion are described as internally unstable. This technical note describes a method for assessing the potential of internal instability of silt-sand-gravel or clay-silt-sand-gravel soils based on their particle size distribution based on laboratory tests carried out by the writers and results published by others. It is shown that some commonly used methods are conservative for these soils.
