摘要:
为研究街道形态影响行人的步行可达性和通风效能,采用计算流体力学(CFD)模拟与空间句法Depth map模拟相结合的方法,探究街道形态风场特征与空间整合度的耦合性关系,总结耦合性规律,得到结论:(1)中间左右错位式的通风效果最明显,但是整合度明显低于前后对齐并列式;(2)建筑前后错接式的通风效果最明显,但是整合度最低;(3)建筑前后错位式的整合度最高,显著高于前后对齐并列式,但是通风效果最差;(4)长街道界面的通风效果较好,但是整合度最低,短街道界面的整合度最高。通过优化街道空间形态,调整建筑形态、建筑布局、沿街界面等措施,使街道活跃度和通风风场相叠合,为行人的步行环境创造良好的通风气候环境。

Abstract:
Street layout affects the pedestrian accessibility and ventilation efficiency. We adopted the method of combining computational fluid dynamics(CFD) simulation and space syntax Depth map simulation to explore the coupling between the characteristics of wind field based on the street layout and space integration index and to summarize the law of coupling. The conclusions are as follows: (1) The ventilation effect of buildings which are staggered left and right in the middle row is the best, but the integration index is significantly lower than that of the aligned ones; (2) The ventilation effect of buildings which are staggered front and back inside is the best, but the integration index is the lowest; (3) The integration index of buildings which are staggered front and back outside is the highest, significantly higher than that of the aligned ones, but the ventilation effect is the worst; (4) The ventilation effect of long streets is better, but the integration index is low, and the integration index of short streets is higher. By optimizing the street space, such as adjusting the building shapes, changing the building layout, and adding interfaces along the streets, the activity in the street and good ventilation can be well correlated, and a better ventilated environment for pedestrians can be created.
