摘　　要：结构风工程研究多在大气边界层风场中进行。合理的大气边界层风场特性是研究的前提。实际风洞通常采用尖劈和粗糙元等被动模拟装置来形成湍流场。本文通过创建TJ-2风洞全尺寸数值模型,精确再现风洞中被动模拟装置布置,模拟得到了符合B类地貌特征的大气边界层风场,模拟结果的平均风剖面和湍流强度剖面与风洞标定试验结果拟合良好,验证了数值风洞方法模拟大气边界层风场的有效性。Structural wind engineering research is mostly carried out in the atmospheric boundary layer wind field.Reasonable atmospheric boundary layer wind field characteristics are the premise of the study.In actual wind tunnels,passive simulation devices such as spikes and rough elements are usually used to form turbulent fields.In this paper,by creating a full-scale numerical model of the TJ-2 wind tunnel and accurately reproducing the layout of the passive simulation device in the wind tunnel,the atmospheric boundary layer wind field that meets the characteristics of type B geomorphology is obtained.The results of the tunnel calibration test are well fitted,which validates the effectiveness of the numerical wind tunnel method in simulating the atmospheric boundary layer wind field.
