1. A wind power plant foundation, comprising a circular or polygonal pedestal divided into several ring sections for carrying a tower and support elements extending radially outward from the pedestal, wherein the ring sections and the support elements are designed as prefabricated concrete elements or are assembled from prefabricated concrete elements, wherein adjacent support elements are spaced from one another in the circumferential direction, and wherein adjacent support elements are each connected with one another by means of a tangentially extending beam designed as a prefabricated concrete element, wherein the tangentially extending beam has a cross-sectional profile with two legs, wherein one leg of the two legs is fixed to the adjacent support elements and the other leg of the two legs forms a support structure that protrudes radially outwardly from the adjacent support elements and is adapted to be supported against the ground, wherein a space between two adjacent support elements is bridged by at least one bridging plate, the at least one bridging plate being designed as a separate concrete element from the two adjacent support elements and bridging the two adjacent support elements without being fastened to said two adjacent support elements, and wherein the at least one bridging plate is supported radially outwardly against the tangentially extending beam such that the tangentially extending beam forms a stop that prevents the at least one bridging element from moving radially away from said space.
