建筑群风环境分层优化策略
|
摘要
为改善建筑群风环境,通过数值模拟技术研究了原始建筑群的风环境情况,并通过分层优化方法改善建筑群的风环境。结果表明,利用分层优化方法对原始建筑群风环境进行优化,使整个研究区域1. 5 m高度处平均风速获得提升效果,风速低于1 m·s-1和高于5 m·s-1的区域面积缩小。可见,分层优化方法有效地改善了建筑群的风环境状况,使行人高度处的风速达到满足人体舒适度的合理阈值。
In order to improve the wind environment of the buildings,the wind environment of the original buildings was studied by numerical simulation technology,and the wind environment of the buildings was improved by the stratified optimization method. The results show that the stratified optimization method is used to optimize the wind environment of the original buildings,so that the average wind speed at the height of 1. 5 meters in the whole study area can be improved,and the area with wind speed below 1 m·s-1 and above 5 m·s-1 is reduced. It is concluded that the stratified optimization method effectively improves the wind environment of the building group,so that the wind speed at the height of the pedestrian is reached to a reasonable threshold to meet the comfort of people.
