. Tab, 5.7 Estimation des déplacements verticaux f XC et f Y C entre les pieux

L. 'ouvrage-Étudié-est-un-remblai-de-un-mètre-d-'épaisseur, . Renforcé-par-pieux, and . Géosynthétiques, Les pieux sont disposés en quinconce. L'espacement entre les pieux est s = 1, 2m. La tête des pieux est ronde de diamètre a = 0

L. Raideur-dans-les, Le sol support est inniment compressible (rigidité nulle) Le sol de remblai a un poids volumique ? de 19kN/m 3 , un angle de frottement interne de 38° et une cohésion c de 13kN

C. Précédemment, expérimentation de Malaisie se fait sur l'essai S Par raison de symétrie, seul un quart de la cuve est modélisée (Fig. 5.51) Les conditions aux limites sont, sur les axes de symétrie, des déplacements horizontaux nuls, respectivement sur x pour les cotés orientés dans la direction y et sur y pour les cotés orientés dans la direction x, Les noeuds de la nappe situés au dessus des pieux sont bloqués verticalement (sur l'axe z), ceux situés sur le pourtour de la cuve sont bloqués dans toutes les directions
