摘　　要：研究了3个土楼建筑群的静力干扰效应,以及受扰建筑屋面风压系数干扰因子的空间分布,分析了不同间距和不同风向角下对建筑群静力干扰效应的影响.结果表明:0°风向角时,增加的施扰体土楼2引起的风干扰较大;45°风向角时,增加的施扰体2土楼是有利干扰;90°风向角时,屋面各分区表面干扰因子在间距为1.0 D时变化不明显;135°风向角时,在土楼群间有很强的巷道风效应产生,干扰因子较大.The static interference effects of three earth buildings and spatial distribution of wind pressure coefficient interference factor of interfered building surface were studied. The influence of different space and wind direction on static interference effect of building group was analyzed. The result showed that the wind interference is obvious, causing by earth building 2, when the direction angle is 0°. The wind interference are good when the direction angles are 45 °. The change of building surface interference factor is not obvious with 1.0 D space,when the direction angle is 90°. Narrow effect is prone to develop and the interference factor is obvious, when the direction angle is 135°.
