摘　　要：对屋面直径为294m的某电厂大罩壳外立面进行了刚性模型风洞测压试验,得到了大罩壳外立面各测点的平均风压系数、点体型系数、各典型风向角下的指定分块体型系数,以及用于结构设计的平均风压以及某风向角下屋面和侧墙风压系数最大值和最小值分布等值线。试验成果对类似圆形大跨度屋盖结构的风压分布具有参考意义。A rigid model wind tunnel pressure test is carried out on the outer facade of the large shell of a power plant with a roof diameter of 294m.The mean wind pressure coefficient,point shape coefficient,and the specified block shape coefficient under each typical wind direction angle at each measuring point of the outer facade of the large are obtained.Mean wind pressure for structural design and contours of maximum and minimum wind pressure coefficients for roof and side walls at a certain wind direction angle are also obtained.The results may provide reference for the wind pressure distribution of similar circular large span roof structures.
