AN ANALYSIS OF THE MULTI-LAYERED SOIL ON MONOPILE FOUNDATION OF OFFSHORE WIND TOWER

摘要

The present invention relates to a method for analyzing a multi-layered ground on a monopole foundation of an offshore wind tower. More specifically, the method comprises: an external strength calculating step of calculating external strength applied to the offshore wind tower; a displacement calculating step of calculating a displacement of a tower base by using the external strength calculated from the external strength calculating step; and a ground reaction calculating step of calculating a ground reaction of the ground by using the displacement calculated from the displacement calculating step. The external strength calculating step comprises: a wind calculating step of calculating wind applied to the tower by wind; a wave strength calculating step of calculating wave strength applied to the power by wave; and a thrust calculating step of calculating thrust applied to the tower by rotation of a blade. Overall substantial external strength applied to a tower of an offshore wind generator is considered, and subgrade reaction is respectively calculated according to a soil constituting the ground. The same may be applied to a multi-layered ground, and an interaction between a base of the tower and the surrounding ground can be accurately analyzed.
