摘　　要：研究单体建筑物高度及并列建筑物高差及并列建筑物间距等因素对并列建筑物周围风场的影响.建立了10组不同的并列建筑群布局,计算采用标准k-ε湍流模型.数值计算得到各种布局下建筑群周围风场,并对它们进行了对比分析.结果表明,单体建筑物高度与并列建筑物高差、并列建筑物间距与单体建筑物高度差共同对并列建筑物周围风场产生影响.The impact of the single building height, the elevation or distance between tWO parallel build- ings on the wind field around two parallel buildings was studied. The standard model was applied in the calculation. The wind fields around buildings were simulated under various layouts. Characteristics of 3D field were discussed and compared with each other. The results show that the factors like the single building height and the elevation between two parallel buildings, the single building height and the dis- tance between two parallel buildings have a synergistic effect on the wind filed.
