板塔混合式高层居住区空间形态与通风效率关联性研究

Research on the Correlation between Spatial Form and Ventilation Efficiency of Slab Tower Mixed High-rise Residential Area

高层住区的室外风环境质量直接关系着居民的生活品质,以武汉地区城市气候为背景,对武汉市中心城区14个板塔混合式高层居住区进行抽样,总结武汉市典型高层居住区建筑空间形态,探讨板塔混合式高层居住区空间形态与通风效率的关系。研究发现,板式高层楼栋数的增加对于行列式板塔混合高层居住区室外低风速区域面积影响不大但能提升通风效率,对于错列式板塔混合高层居住区则会增加其室外低风速区域面积,降低其风阻指数,但降低幅度要小于行列式建筑布局。研究结论可为夏热冬冷地区其他城市提供一定参考。

The quality of the outdoor wind environment in high-rise settlements is directly related to the quality of life of the residents.Taking the urban climate of Wuhan as the background,14 mixed-type high-rise districts with slab and tower in central Wuhan were sampled to summarise the spatial morphology of typical high-rise districts in Wuhan,and to explore the relationship between spatial morphology of the mixed-type high-rise districts with slab and tower and the efficiency of ventilation.It is found that an increase in the number of slab-type high-rise buildings has little effect on the area of outdoor low-wind areas of row-type slab-tower hybrid high-rise residential areas but can improve the ventilation efficiency,while a staggered row-type slab-tower hybrid high-rise residential area increases the area of outdoor low-wind areas and reduces the wind resistance index,but the level of the reduction is smaller than that of the row-type building layout.The conclusions of the study provide some references for other cities in hot summer and cold winter regions.
