摘　　要：采用数值模拟方法对由6幢方形截面高层建筑组成的建筑群的周围风环境进行了计算和分析。6幢建筑起初呈两行三列布置,通过改变各列建筑的横向间距,得到了6种不同布局型式的建筑群。对各建筑群周围人行高度处的风速比和风速矢量场进行了计算和分析、比较,据此对不同布局形式的建筑群的风环境状况作了评价,提出了通过调整平面布局改善高层建筑群风环境的措施和建议。Numerical simulation is carried out to investigate the wind environment around a building complex consisting of six rectangular tall buildings. The six buildings are initially arranged in two rows and three columns. By altering the distance between the two adjacent buildings in each column, six types of building complexes with different plan layout are obtained. The wind-velocity ratios and corresponding velocity vector field in the area at the pedestrian height level (2.0m) surrounding each building complex are examined and compared with each other. The wind environment conditions of the six building complexes are estimated and several suggestions for improving the wind environment conditions by adjusting the plan arrangement are proposed.
