摘要
为研究单一荷载作用下海上风机桩基的承载性能,文中通过有限元软件分析海上桩基在不同类型荷载作用下的承载性能,以及不同桩径对桩基承载能力的影响.研究结果表明,海上桩基的竖向极限承载能力可根据竖向变形进行控制,桩基在力矩荷载作用下主要发生渐进式破坏,选择合适的桩径能有效提高海上桩基在各个方向的承载能力.
Abstract
In order to study the bearing capacity of offshore wind turbine pile foundation under single load,this paper analyzes the bearing ca-pacity of offshore pile foundation under different types of loads by finite element software,and analyzes the influence of different pile diameters on the bearing capacity of pile foundation.The results show that the vertical ultimate bearing capacity of offshore pile foundation can be con-trolled according to the vertical deformation.The pile foundation mainly undergoes progressive failure under the action of moment load.Choo-sing the appropriate pile diameter can effectively improve the bearing capacity of offshore pile foundation in all directions.
