[Influence de l'indice des vides inter-granulaire sur la réponse monotone et cyclique non draine des sols sableux]
La liquéfaction des dépôts de sols sableux pendant les séismes a toujours été l'un des problèmes les plus importants dans le domaine de la géotechnique. Un défi important est l'évaluation de la resistance au cisaillement non drainée appropriée des sols liquéfiables à utiliser dans l'étude de la stabilité de liquéfaction de différents types d'ouvrages en terre (remblais, barrages en terre, etc.). L'objectif de ce travail expérimental est d'étudier l'effet de l'indice des vides intergranulaire sur la résistance au cisaillement non drainée mesurée en changement de phase des mélanges de sable–limon lâche, moyennement dense et dense (
Liquefaction of sandy soil deposits during earthquakes has been one of the most important problems in the field of geotechnical earthquake engineering. A major challenge is the assessment of the appropriate undrained shear strength of liquefied soils to be used in the study of liquefaction stability of different types of earth structures (embankments, earthdams, etc.). The objective of this laboratory investigation is to study the effect of the inter-granular void ratio on the phase transition state undrained shear strength of loose, medium dense and dense (
