摘　　要：以鄂尔多斯国泰商务广场工程为背景,基于雷诺平均方法(RANS)和标准k-ε湍流模型,对多塔高层建筑周围的风场进行了数值模拟,得到不同风向角下建筑表面风载体型系数.然后,对串列与并列布置两种工况下的风场分布特性进行了分析,且阐明了塔楼之间风场的互扰机理.通过与风洞试验结果的对比表明数值模拟的结果能较准确地获取多塔高层建筑结构表面风压分布,为此类建筑结构的抗风设计提供一定依据.Based on the project of Ordos Guo Tai Business Plaza,the wind field around the multi-tower tall building is simulated by Reynolds-Averaged Navier-Stokes method and standard k-εturbulent model,while the wind loading shape coefficient distribution of structural surface at different wind angles is obtained.Then,the characteristics of wind field under different arrangement cases are analyzed and the mechanism of interference effects between towers is revealed.Compared with the data obtained from wind tunnel test,it shows that the computational results could accurately obtain the pressure distribution of the multitower tall building,providing a reference for wind-resistant design of such building.
