摘要
近年来,随着国家对清洁能源重视程度的提高,海上风电迎来了巨大的发展机遇。本文对海上风电机组多桩承台基础桩基进行了受力分析,利用SESAM海工结构软件建立了多桩承台基础有限元模型,建模时考虑了风波流等环境荷载。选取桩倾斜率、桩长、桩径作为基本参数,分析了其对桩基承载能力、基础水平位移的影响。通过参数分析,得到了一些基本结论,这些结论可以为多桩承台基础的设计提供一定的参考。
In recent years,with the increase of national attention to clean energy,offshore wind power has ushered in great development opportunities.In this paper,the analysis of the pile force of multi-pile cap foundation of offshore wind turbines is carried out,and the finite element model of multi-pile cap foundation is established by using SESAM marine structure software.The environmental loads such as wind,wave and current are considered in the modeling.The pile inclination rate,pile length and pile diameter are selected as the basic parameters,and their effects on the bearing capacity of pile foundation and horizontal displacement of foundation are analyzed.Through parameter analysis,some basic conclusions are obtained,which can provide some reference for the design of multi-pile cap foundation.
