摘要:
道口镇,作为大运河永济渠段重要的历史村镇,具有“三街六铺七十二胡同”的传统街巷空间结构.采用CFD技术研究了道口镇顺河北街片区街巷空间风环境特征,解析了街巷空间风环境与街巷空间特征、街巷尺度的关系.研究结果表明街巷的开敞空间、拐角空间及入口空间的通风效果较好,不同季节街巷尺度与街巷空间舒适风的关系具有较为明显的差异.在夏冬两季,街巷宽度一定时建筑高度与舒适风速比率呈正相关; 建筑高度一定且街巷宽度在1.3～2.0 m之间时,舒适风速比率随着街巷宽度的增加呈先增加后减小的趋势; 建筑高度一定且街巷宽度在2.0～5.0 m之间时,舒适风速比率随街巷高宽比的增加呈先增加后减小的趋势.而在春季,当街巷宽度在1.3～2.0 m之间且建筑高度不为9 m时,街巷宽度一定舒适风速比率随着建筑高度的增加呈先减小后增加的趋势; 建筑高度一定舒适风速比率与街巷宽度呈正相关,与街巷高宽比呈负相关.
Abstract:
Daokou Town, as an important historical village in the Yongji Canal section of the Grand Canal, has a traditional spatial structure of “three streets, six stores and seventy-two alleys”. In this paper, CFD technology is used to study the characteristics of street spatial wind environment in the North Shunhe Street area of Daokou Town, and the relationship between street and alleys spatial wind environment and its spatial characteristics and scale is analyzed. The research results show that the ventilation effect of the open space, corner space and entrance space of the street is better, and the relationship between the street scale and the comfortable wind of the street space has more obvious differences in different seasons. In summer and winter, the building height is positively correlated with the comfortable wind speed ratio when the street width is constant; when the building height is constant and the street width is between 1.3 m and 2.0 m, the comfortable wind speed ratio increases first and then decreases with the increase of street width; when the building height is constant and the street width is between 2.0 m and 5.0 m, the comfortable wind speed ratio increases first and then decreases with the increase of the street aspect ratio. But in spring, when the street width is between 1.3 m and 2.0 m and the building height is not 9 m, the comfortable wind speed ratio of the street width decreases first and then increases with the increase of the building height; the comfortable wind speed ratio of the building height is positively correlated with the width of the street and negatively correlated with the aspect ratio of the street.
