Abstract
Il est décrit une fondation de turbine éolienne en mer pour une couche de revêtement peu profonde et son procédé de construction, la fondation de turbine éolienne en mer ayant un pieu unique. Un disque de gravité est monté à demeure sur le pieu unique. Plusieurs pieux hélicoïdaux sont répartis de manière uniforme sur la périphérie du disque de gravité. Des pieux hélicoïdaux adjacents sont reliés à demeure les uns aux autres pour former une structure intégrale. La capacité portante résistante au soulèvement et la capacité portante horizontale de la fondation sont améliorées par les pieux hélicoïdaux et le disque de gravité. Le déplacement horizontal du corps de pieu et le moment de flexion du corps de pieu sont réduits. La combinaison et la liaison rigide des pieux hélicoïdaux, du disque de gravité et du pieu unique améliorent diverses propriétés mécaniques de l'ensemble de la fondation. Par conséquent, l'exigence de construction pour un fonctionnement sûr et stable d'une éolienne en mer puisse être satisfaite sans avoir besoin d'insérer le pieu unique dans le substratum rocheux.
