摘　　要：研究品字形建筑群静力干扰效应,以及受扰建筑表面风压系数干扰因子的空间分布,分析建筑相对位置变化对静力干扰效应的影响.结果表明,建筑物串联布置且间距较小时,遮挡效应明显;建筑间斜列布置时,静力干扰效应减弱;建筑间并列布置时,容易发生狭缝效应.对于成品字形建筑群,下两建筑对上一建筑的干扰效应具有遮挡效应又有狭缝效应.受扰建筑表面风压的干扰因子,其分布沿高度和宽度的不同位置而变化显著.The static interference effects of buildings with‘∴’arrangement and spatial distribution of wind pressure coefficient interference factor of interfered building surface is studied,the influence of the relative distance of building no static interference is analyzed.The results show：static interference is obvious when buildings arrangement string in line with small distance;static interference weakens gradually when buildings arrangement is in oblique line;narrow effect is prone to develop when buildings arrangement is in parallel.As for buildings with‘∴’arrangement,the lower two buildings show shield effect and narrow effect simultaneously to the upper building.The distribution of wind pressure coefficient interference factor of interfered building surface changes obviously along height and width.
