Titre : Compression and creep of venice lagoon sands Type de document : texte imprimé Auteurs : Alex Sanzeni, Auteur ; Andrew J. Whittle, Auteur ; John T. Germaine, Auteur Année de publication : 2013 Article en page(s) : pp.1266–1276. Note générale : Géotechnique Langues : Anglais (eng) Mots-clés : Sand compression Creep Soil behavior Model calibration Venice Lagoon Résumé : A laboratory test program was conducted to evaluate the one-dimensional (1D) compression and creep properties of intact sand (and silty-sand) samples from a deep borehole at the Malamocco Inlet to the Venice Lagoon. The tests were performed with a constant rate of strain consolidometer and included special procedures for trimming the frozen samples and measuring strains during thawing and backpressure saturation. The specimens had variable fine fractions ranging from 6 to 21% and mica contents ranging from 1 to 10%. The results confirmed that there is a strong correlation between the creep rate coefficient and the compressibility index and between the swelling index and mica content. The compression behavior in all tests is well described by a nonlinear compression model with a unique limiting compression curve and a variable transition parameter that reflects the fines and mica content. Creep tests performed at different confining pressures are also well represented by a simple two-parameter model.
