采用标准k-ε湍流模型，对南昌“云中城”项目中高层建筑进行了风荷载数值模拟分析，得出了两座办公塔楼表面各测点间的风压值。通过计算导出了两座塔楼的风荷载体型系数的最大绝对值，并与规范中单体建筑物的风荷载体型系数进行了比较，得出，群体产生的湍流效应对建筑物的风荷载体型系数影响不可忽视，同时还受建筑间距的影响。

According to the standard k-εturbulence model, this study carried out numerical simulation and analy?sis of wind load on the high-rise buildings of Cloud City Project in Nanchang and found out the wind pressure val?ue at measure points of the two office building surface. Then it obtained the maximum absolute value of wind load shape coefficient of two buildings through calculating and compared it with that of single building in relevant speci?fications. Finally, it draws a conclusion that the turbulence effects resulting from community on wind load shape coefficient of buildings can not be neglected. Meanwhile it also maintains that wind load model coefficient is also influenced by the building interval.
