摘　　要：海上风电基础设计状况通常包括偶发极端状况、正常使用极限状况等。承载能力极限状态验算时风电机组荷载应取风电机组极限荷载设计值,正常使用极限状态验算时风电机组荷载应取风电机组极限荷载标准值。基于明阳青洲四海上漂浮研发项目,通过理论建模、数值仿真等方法,综合分析在位承载力的潜在影响因素以及不同荷载工况条件下的吸力锚及地基的受力特性等,从而综合评价本吸力锚基础结构设计方案。The design conditions of offshore wind power foundations usually include occasional extreme conditions, normal usage limit conditions,etc.When checking the ultimate limit state of bearing capacity,the load of wind turbines should be taken as the design value of the ultimate load of wind turbines.When checking the ultimate limit state of normal use,the load of wind turbines should be taken as the standard value of the ultimate load of wind turbines.This article is based on the Mingyang Qingzhou Four Seas Floating Research and Development Project.Through theoretical modeling, numerical simulation and other methods, the potential influencing factors of in-situ bearing capacity and the stress characteristics of suction anchor and foundation under different load conditions are comprehensively analyzed to comprehensively evaluate the design scheme of the suction anchor foundation structure.
