Abstract:
1. A foundation for enabling anchoring of a wind turbine tower thereto by means of replaceable through-bolts, comprising: a foundation sole including a set of through-holes for accommodating the through-bolts, wherein said through-holes extend from an upper surface to a lower surface of said foundation sole; a set of hollow tubes extending from the lower surface to the upper surface of said foundation sole thereby defining said through-holes in said foundation sole; a load distributing member arranged at a lower surface of said foundation sole for distributing stress generated at the lower ends of the through-bolts over a larger area of said foundation sole, said tubes arranged on said load distributing member in such a way that a bore of each tube coincides with a through-hole in said load distributing member; a workspace arranged beneath said foundation sole for enabling access to lower ends of the through-bolts when arranged in said through-holes; and a passage which does not pass through said foundation sole allowing access to said workspace from a location outside an area of the foundation sole to be covered by the tower.
