水平静荷载作用下翼板对基桩工作性状影响的有限元研究
Finite element analysis of the impact of wing plates on laterally loaded foundation pile
摘要
Abstract
Pile foundation of offshore wind turbines is mainly used to sustain lateral loads and moments. As an attempt, by increasing the effective contact between pile and soil with the wing plates, the lateral bearing capacity of large diameter foundation pile can be improved. In this paper, the impact of wing plate area and the ratio of length and width on the lateral bearing capacity of pile were analyzed based on the Mohr-Coulomb elastoplastic soil model of ABAQUS. The results show that the lateral displacement and moment of the pile reduce significantly when the wing plates are disposed on soil surface, and the reduction of the lateral displacement is more obvious than the mo⁃ment. For the square wing plate, the side length is not suggested to be longer than 1.6D, since the impact of wing plates on increasing the lateral bearing capacity is not obvious when the length is over 1.6D. For rectangular wing plate, the increase of the lateral bearing capacity of the prolate shape is more apparent than the vertical elongate shape.关键词
