摘　　要：运用ICEM CFD-CFX软件,采用SSTk-ω湍流物理模型,模拟了较高层建筑物对常见的轻型门式刚架双坡屋面的风压影响,得到在不同的间距下,双坡屋面随风向角变化的风压分布特性及变化规律.The numerical simulation techniques of ICEM CFD-CFX are employed to study the wind pressure effect of the downstream tall building on the upstream low building while turbulence model SST is used. At different patches of the two buildings the rule that wind pressure changes with the variety of angles is obtained. Via analysis of the baring effect of downstream tall building on upstream low building, we obtained the distribution characteristics and change law of the wind pressure of the dual-slope roof.
