The invention relates to a method for building a foundation for a structure comprising a plurality of segments, in particular for a wind
turbine tower, a foundation segment for use in such method, and a wind
turbine. In order to create a stable foundation, a method comprising the following steps is proposed on the basis of experience gained:_excavating a foundation
bed,_building a stable, substantially level and horizontal
subbase in a foundation
bed, setting down a foundation segment of the structure on the
subbase, wherein at least three vertically adjustable support poles are fixedly attached to said foundation segment by means of a supporting bracket mounted at the end of the support poles in such a way that only the support poles are placed onto predetermined points of support on the
subbase,_producing a reinforcement on the subbase,_filling the remainder of the foundation
bed with foundation
mass, in particular concrete, to a level above the bottom rim of the foundation segment.
