摘　　要：无锡蠡湖科技大厦刚性模型的风洞试验测量了模型表面的平均和脉动风压,给出了不同风向角下各测点的平均风压系数和体型系数。讨论了风场和风向角对平均风压系数和体型系数的影响,以及两个正方形截面塔楼的相互气动干扰影响特点,得到双塔高层建筑中各单塔楼的总体体型系数大于单体建筑的结论。In the wind tunnel test of the rigid model for Wuxi Lihu Technology Building, the average and fluctuating wind pressure on the model surface are measured. The coefficients of the average wind pressure and the shape coefficient of wind load at each monitoring points under different wind angles and the shape coefficient of wind load at each floor are achieved in the test. The influence of wind field and wind angle on the coefficients of the average wind pressure and shape coefficient, as well as the aerodynamic interaction between two square section towers are discussed. The feasibility of the application of the shape coefficient of wind load on the structure design are analysed. It was concluded that the shape coefficient of the one of double towers is greater than that of the single tower.
