Abstract

Abstract

The impact of diameters of piles, wall thickness of tubular steel piles and layout radii of piles for high-rise pile cap foundations of offshore wind turbines on the static performances and load effects of piles were analyzed by the SESAM software. The results indicated that: in certain conditions of external loads and environmental parameters, the changes in diameters of piles, wall thicknesses and layout radii of tube piles had different influences on the axial compression, axial tension, shear force and bending moment of the structure. Based on the calculation data, an optimized design method for the structure was proposed. By analyzing the rules of the vertical and horizontal displacement and rotation angle at the mud surface in changes of the structural parameters, the regression curves were obtained, which were verified by examples in different sea conditions and was of good accuracy.
