Abstract

La présente invention se rapporte à un procédé de terrassement d’une fondation conçue pour former un massif pour une éolienne terrestre, comprenant une étape d’excavation dans le sol (S) d’un renfoncement (Rf) destiné à réceptionner, d'une part, un moyen d’ancrage (Cg) qui va être utilisé pour lier le mât à la future fondation, et d'autre part, un coulage de béton (B) pour former après durcissement ladite fondation ; selon l’invention, le procédé consiste - à creuser au niveau du centre du renfoncement (Rf), un décaissement (Dc), - à déposer dans ce décaissement (Dc), un matériau compressible, - à recouvrir ledit matériau d’une couche de béton (Bt3) et attendre son durcissement, Un terrassement ainsi élaboré permet la construction d’une fondation pour une éolienne, notamment par un coulage de béton, et dont la partie centrale ne prend pas appui sur le sol ou prend un appui négligeable sur le sol. Il en résulte que la pression au sol est accrue et délimitée sur une zone annulaire périphérique située autour de sa partie centrale. Cette répartition annulaire des charges permet à la fondation d’accepter une excentricité de charges plus importante. On peut dès lors réduire le diamètre de la fondation, réduire le volume de béton entrant dans sa fabrication. Fig. 6
