Parameters controlling stiffness and strength of artificially cemented soils / N. C. Consoli in Géotechnique, Vol. 62 N° 2 (Fevrier 2012) 

Public ISBD [article]  in Géotechnique > Vol. 62 N° 2 (Fevrier 2012) . - pp. 177 –183 Titre : Parameters controlling stiffness and strength of artificially cemented soils Type de document : texte imprimé Auteurs : N. C. Consoli, Auteur ; A. V. Da Fonseca, Auteur ; S. R. Silva, Auteur Année de publication : 2012 Article en page(s) : pp. 177 –183 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Soil  stabilisation  Sands  Ground  improvement  Stiffness  Laboratory  tests  Compaction Résumé : The treatment of soils with cement is an attractive technique when a project requires improvement of the local soil for the construction of subgrades for rail tracks, for roads, as a support layer for shallow foundations, and to prevent sand liquefaction. This paper advances understanding of the key parameters for the control of strength and stiffness of cemented soils by testing two soils with different gradings and quantifying the influence of porosity/cement ratio on both initial shear modulus (G 0) and unconfined compressive strength (q u). It is shown that the porosity/cement ratio is an appropriate parameter to assess both the initial stiffness and the unconfined compressive strength of the soil–cement mixtures studied. Each soil matrix has a unique relationship for G 0/q u against adjusted porosity/cement ratio, linking initial stiffness and strength.

The mechanics of fibre-reinforced sand / A. P. S. Santos in Géotechnique, Vol. 60 N° 10 (Octobre 2010) 

Public ISBD [article]  in Géotechnique > Vol. 60 N° 10 (Octobre 2010) . - pp. 791-799 Titre : The mechanics of fibre-reinforced sand Type de document : texte imprimé Auteurs : A. P. S. Santos, Auteur ; N. C. Consoli, Auteur ; B. A. Baudet, Auteur Année de publication : 2011 Article en page(s) : pp. 791-799 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Reinforced  soils  Sands  Laboratory  tests Index. décimale : 624 Constructions du génie civil et du bâtiment. Infrastructures. Ouvrages en terres. Fondations. Tunnels. Ponts et charpentes Résumé : Fibres can be an effective means of reinforcing soils. This paper presents data from laboratory triaxial tests on quartzitic sand reinforced with polypropylene fibres. By keeping the studied composite consistent throughout the study (host sand and fibre characteristics kept constant), it has been possible to develop a framework of behaviour for the sand–fibre material, which provides a solid base for future research on fibre-reinforced soils. Data from previous work and from new tests have been analysed within the Critical State framework, that is in terms of normal compression line, critical state line and state boundary surface.
