摘　　要：设计了一种可用于建筑风环境测试的风洞试验方法,利用不等间距的格栅制造大气边界层的风速剖面,采用此方法的风洞试验平台具有占地面积小、节约运行成本、能够快速构建不同地貌类型大气边界层的梯度风等优点。A wind tunnel test method which can be used for the building wind environment detection is designed. The wind velocity profiles of the atmospheric boundary layers are created by using unequal spacing gratings. The wind tunnel test platform with this method has the advantages of small area occupation,the operational cost saving,the rapid construction of the gradient wind in atmospheric boundary layers with different landform types,etc.
