摘　　要：本文通过CFD数值模拟两栋前后串列的高层建筑之间的风荷载气动干扰,并对高层建筑附近压力分布以及流场特性进行分析。通过与单体建筑的计算结果进行对比发现,串列的两高层建筑,上游建筑受干扰小,而下游建筑受上游建筑的影响显著,尤其是顺风向阻力作用。The wind load between two tall tandem buildings was investigated based on CFD numerical simu-lation in this paper. The pressure distribution and the characteristics of flow field around two high-rise buildings in tandem arrangement were analyzed compared with the calculation results with monomer building, which revealed that the upstream construction had a small disturbance. But, the downstream construction was largely affected by the upstream building, especially for the drag.
