MONOPILE TYPE FOUNDATION STRUCTURE OF WIND POWER GENERATION FACILITY

摘要

PROBLEM TO BE SOLVED: To provide a monopile type foundation structure of wind power generation facility on the land or sea.

SOLUTION: When the ground is constituted by accumulating a soft layer on a supporting layer, the ground is improved in a region of the soft layer around a section in which a monopile is embedded in a scope of the whole region of height of the soft layer in the direction of depth up to a fixed scope in the horizontal direction to ensure supporting force in the horizontal direction required to support the monopile. The monopile is partially embedded up to a depth by which it reaches the supporting layer of the ground in a scope of ground improvement in substantially a central part of ground improvement. The monopile is formed to have such a diameter and wall thickness that withstand the load of the wind power generation facility and external force such as wind sufficiently.
