摘　　要：用数值模拟方法预测了上海久事大厦周围的风流场 ,并将建筑物表面平均风压的数值模拟与风洞试验结果进行了比较研究 ,两者结果吻合。同时进行了上海久事大厦周围高层建筑干扰影响的研究 ,并给出了湍流物理模型的建议。研究表明 。The wind flow field around Jiushi mansion in Shanghai is predicted with numerical simulation method.Distribution of wind pressure on the building surfaces is compared with the results of wind tunnel test and they correspond well with each other.Research on the interference of surrounding tall buildings to Jiushi is carried out, and the suggestions on the choice of turbulence model are presented.It is concluded that the application of progressive numerical simulation on wind engineering of tall buildings is feasible.
