该文通过计算流体力学数值模拟技术对某超高层建筑进行了表面风荷载分布的数值模拟。结果表明：由于漩涡脱落，在结构侧面边缘出现了较强烈的负压区；在周边建筑干扰高度范围内，结构表面风压分布较混乱，结构在干扰高度以上部分风压分布比较规律；局部部位的设计风压应参考各风向角下风压峰值。

The surface wind pressure distribution of a super high-rise building is simulated numerically through computational fluid dynamics numerical simulation technology. The results show that a negative pressure region appears at the side of the structure because of vortex shedding, the surface wind pressure distribution on the super high-rise building is in disorder within the range of the interference height of surrounding buildings, but the wind pres-sure is regularly distributed when the structure is above the interference height, and the wind pressure peak value at different wind directions should be referenced in structure design to determine the local wind pressure.
