A wind turbine foundation having a central pedestal, a bottom support slab, and a plurality of prefabricated radial reinforcing ribs. The pedestal and support slab are poured in situ at the site. When the concrete cures the support slab is united to the prefabricated ribs and the ribs are also united to the pedestal. The result is a continuous monolithic foundation wherein loads are carried across the structure vertically and laterally through the continuous structure by doweled and spliced reinforcing steel bars which are integrally cast into the pedestal, ribs and support slab. The slab thus behaves structurally as a continuous slab reducing deflections, improving fatigue conditions and increasing the stiffness of the foundation as well as allowing for the benefits of an economical design.
Fondation pour turbine éolienne comportant un socle central, une dalle d'appui inférieure, et une pluralité de nervures de renfort radiales préfabriquées. Le socle et la dalle d'appui sont coulés in situ sur le chantier. Lorsque le béton durcit, la dalle d'appui se joint aux nervures de renfort préfabriquées, lesquelles se joignent à leur tour au socle, en formant ainsi une fondation monolithique continue comportant des barres d'armature en acier assemblées par goujons incorporées dans le socle, les nervures et la dalle d'appui dans le but d'assurer une répartition verticale et latérale des charges dans la structure continue. Le comportement structurel de la dalle est donc celui d'une dalle continue, ce qui permet de réduire les risques de fléchissement, d'améliorer les limites de fatigue et d'accroître la rigidité de la fondation de façon économique.
