摘　　要：针对超大型浮式平台上层建筑台风状态下风载荷,分别采用中国船级社(CCS)、挪威船级社(DNV)规范和实尺度计算流体动力学(Computational Fluid Dynamics,CFD)计算等3种方法进行计算,并对计算结果进行对比分析。CFD方法与DNV规范方法计算结果较为一致,当风向角为135°和225°时最大误差为10.19%,在其他风向角时误差小于8%。构建平台空间位置风载荷影响分析方法,可通过云图形象直观地看出不同风向角下平台横向和纵向空间位置对风载荷的贡献量及模块间遮蔽效应的影响程度。研究成果可为平台设计人员更合理地评估风载荷提供参考,为进一步优化平台上层建筑构型提供指导。Regarding the wind load on the superstructure of the ultra-large floating platform under typhoon conditions,three methods of CCS,DNV standards and real-scale Computational Fluid Dynamics(CFD)calculation are used to carry out the calculations,and the calculation results are compared and analyzed.The calculation results of CFD method and DNV standard method are relatively consistent,the maximum error is 10.19%at wind angles of 135°and 225°,and less than 8%for other wind direction angles.A method is constructed for analyzing the influence of the wind load on the spatial positions of the platform,and the contribution of the horizontal and longitudinal spatial positions of the platform to the wind load and the degree of inter-module shielding effect can be visually seen through cloud images.The research results can provide reference for the platform designers to evaluate wind load more reasonably and provide guidance for further optimizing the configuration of the platform superstructure.
