两个相邻高建筑物周围的风环境

描述研究了建筑物周围人行道高度风速分布特征的风洞模拟实验。结果表明：在一个横风向宽度很大的高大建筑物的迎风面拐角附近，风速增大约１倍；而在建筑物的前方有风速的骤变区，这均形成严重的风环境问题。当用一通道将该建筑物分割成两个相邻建筑物时，上述两方面的风环境问题得到了有效的改善，且通道宽度与建筑物顺风向尺度之比的优化数值在１８至２４之间

WIND ENVIRONMENT AROUND TWO NEARBY HIGH BUILDINGS

This paper describes the experimental study with environmental wind tunnel on the pedestrian level wind environment around buildings.Followings are testing results:A high building with very large cross\|wind dimension produces high speed\|up of comer wind and wind gradient area in front,which results in serious wind environmental problems.Dividing the building into two nearby buildings by a narrow channel effectively improves the problems while an optimum value for the ratio of channel width to its length lies from 1.8 to 2.4.
