Influence of hydro-mechanical coupling on tunnel response in clays / Alessandro Graziani in Journal of geotechnical and geoenvironmental engineering, Vol. 138 N° 3 (Mars 2012) 

Public ISBD [article]  in Journal of geotechnical and geoenvironmental engineering > Vol. 138 N° 3 (Mars 2012) . - pp. 415-418 Titre : Influence of hydro-mechanical coupling on tunnel response in clays Type de document : texte imprimé Auteurs : Alessandro Graziani, Auteur ; Daniela Boldini, Auteur Année de publication : 2012 Article en page(s) : pp. 415-418 Note générale : Géotechnique Langues : Anglais (eng) Mots-clés : Deep  tunnels  Clayey  soils  Hydro-mechanical  coupling  Analytical  solutions  Numerical  modeling Résumé : The design of deep tunnels underneath the water-table in clayey soils should carefully take into account the influence of pore pressures and seepage forces on the stability of the excavation and on the loading conditions of the support systems. This paper focuses on the application of analytical solutions and numerical models to the analysis of stress and deformation around deep tunnels, in the short and long term, considering the idealized situation of axisymmetric conditions. General remarks on the influence of hydro-mechanical coupling, artificial boundary conditions and lining permeability are presented. Theoretical predictions are compared with measurements made in tunnels excavated in the Boom clay formation at Mol (Belgium).
