A foundation for a structure comprises a plurality of segments. To build the foundation, a foundation bed is excavated, and a stable, substantially level and horizontal subbase is built in the foundation bed. A foundation segment of the structure is set down on the subbase, such that at least three vertically adjustable support poles fixedly attached to the foundation segment contact reinforced points of support on the subbase. A remainder of the foundation bed is then filled with foundation mass to a level above a bottom rim of the foundation segment.

The invention claimed is: 1. A method for building a foundation for a structure comprising a plurality of segments, comprising: a) excavating a foundation bed; b) building a stable, substantially level and horizontal subbase in the foundation bed; c) 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 supporting brackets mounted at ends of the support poles in such a way that only the support poles are set down onto predetermined points of support on the subbase; d) producing a reinforcement on the subbase; and e) filling a remainder of the foundation bed with foundation mass to a level above a bottom rim of the foundation segment by: casting in foundation mass until approximately the bottom rim of the foundation segment is reached; after casting in foundation mass until approximately the bottom rim of the foundation segment is reached, vertically aligning the foundation segment; and after vertically aligning the foundation segment, filling the remainder of the foundation bed with foundation mass. 2. The method of claim 1, further comprising attaching each of the support poles by support plates to a flange proximate the bottom rim of the foundation segment. 3. The method of claim 1, further comprising vertically adjusting the support poles, each having an internal threaded pole, using a vertical adjustment device disposed at a lower end of the support poles facing the subbase. 4. The method of claim 1, further comprising mounting each of the support poles on a flange at an upper rim of the foundation segment. 5. The method of claim 4, wherein mounting each of the support poles includes passing the support poles through eyes on the bottom rim of the foundation segment and into the foundation segment. 6. The method of claim 1, wherein producing the reinforcement on the subbase includes mechanically reinforcing the points of support on the subbase. 7. The method of claim 1, further comprising: stringing reinforcement wire through holes in side walls of the foundation segment, wherein filling the remainder of the foundation bed further includes filling the remainder of the foundation bed with foundation mass to such a height that the holes are covered over by foundation mass. 8. The method of claim 1, further comprising: measuring heights of the supporting brackets using an optical measurement system; and adjusting the heights of said supporting brackets based at least in part on the measured heights. 9. The method of claim 8, wherein measuring the heights of the supporting brackets includes: directing a light beam in a horizontal direction from a light source disposed inside the foundation segment towards a first one of the supporting bracket; sensing the light beam at the first supporting bracket using an optical sensor; and generating a sensor signal at the optical sensor, the sensor signal indicative of a height of the first supporting bracket; and wherein adjusting the heights of said supporting brackets includes adjusting the height of the first supporting bracket based at least in part on the sensor signal. 10. The method of claim 9, wherein adjusting the heights of said supporting brackets includes adjusting the height of the first supporting bracket using an electric motor responsive to the sensor signal. 11. A foundation for a structure comprising a plurality of segments, the foundation comprising: a subbase positioned in a foundation bed, the subbase including a plurality of reinforced points of support; a foundation segment having a circumferential row of holes in side walls of the foundation segment; at least three vertically adjustable support poles fixedly attached to the foundation segment by support plates mounted at ends of the support poles, the support poles contacting the reinforced points of support; and reinforcement steel extending through the circumferential row of holes. 12. The foundation of claim 11, wherein at least one of the support poles comprises: an outer pipe coupled to one of the support plates; a foundation plate; and a threaded pole displaceable inside the outer pipe, the threaded pole connected between the one of the support plates and the foundation plate and configured to change a gap between the one of the support plates and the foundation plate. 13. The foundation of claim 12, further comprising a base plate at an end of the support pole. 14. The foundation pole of claim 12, further comprising an electric motor configured to drive the threaded pole to change the gap between the one of the support plates and the foundation plate. 15. The foundation of claim 14, further comprising an optical sensor coupled to the one of the support plates and to the electric motor, the optical sensor configured to generate a signal indicative of a height of the one of the support plates, wherein the electric motor is further configured to drive the threaded pole based at least in part on the signal from the optical sensor. 16. The foundation of claim 15, wherein the optical sensor has a plurality of optical sensor elements arranged along a longitudinal direction of the at least one support pole. 17. A wind turbine having a tower comprised of a plurality of segments, the tower including the foundation of claim 11.
