Offshore wind generator single pile base structure with stabilizer fin

Abstract

The invention relates to an offshore wind generator single pile base structure with a stabilizer fin, solving the technical problem of providing an offshore wind generator single pile base structure with a stabilizer fin, and aiming to improve the horizontal bearing performance of a fan base, improve the horizontal bearing force of a base pile and lower the displacement and the bending moment of the pile body. The technical scheme for solving the problem comprises: a group of stabilizer fins are additionally arranged on the elevation near the ground surface below a seabed mud surface and on the body of the base pile, the stabilizer fins are radially arranged by taking the base pile as the center, the length direction is parallel to the axial direction of the base pile, and the width direction is vertical to the axial direction of the base pile. The invention is suitable for the industry of offshore wind power generation, in particular the single pile fan base with a large pipe diameter.

Description

technical field [0001] The invention relates to a single-pile foundation structure of an offshore wind power generator with stabilizing wings, which is suitable for the offshore wind power generation industry, especially the single-pile wind turbine foundation with a large pipe diameter. Background technique [0002] The monopile foundation is usually composed of a single large-diameter steel pipe. The lower part goes deep into the soil to provide bearing capacity; the middle part is immersed in water to withstand long-term cycles such as waves, ocean currents, and tides; the upper part is connected to the wind tower through a connecting section. As the simplest structure type of offshore wind power foundation, single column and single pile foundation is the dominant foundation structure type of European offshore wind farms. With the improvement of domestic pile making technology and pile sinking ability, single pile foundation will also become the main structural type in th...

AI Technical Summary

Problems solved by technology

[0003] Offshore wind power structures are mainly subjected to horizontal loads such as wind, waves, and currents. The horizontal bearing performance of foundation piles needs to be considered in the design. For large-diameter single pile foundations, due to their "softness" (relatively small The response of the dynamic load is relatively large, and it is easy to cause fatigue damage or even failure under the long-term action of dynamic loads such as wind, waves, and currents; and the horizontal displacement of the pile body is not easy to control
