【摘要】：建筑風(fēng)環(huán)境主要包括室外風(fēng)環(huán)境和室內(nèi)自然通風(fēng),室外風(fēng)環(huán)境關(guān)系到行人舒適性問題甚至是安全問題。建筑風(fēng)環(huán)境與建筑物的外形、尺寸、建筑物之問的相對(duì)位置以及周圍的地形地貌有著很復(fù)雜的關(guān)系。本文主要通過一系列的風(fēng)洞試驗(yàn)來模擬與分析高層建筑與住宅小區(qū)人行高度處風(fēng)環(huán)境的相互影響。 研究高層建筑對(duì)小區(qū)周圍人行高度處風(fēng)環(huán)境的影響時(shí),以住宅小區(qū)橫向通道、縱向通道及拐角區(qū)域三個(gè)區(qū)域?yàn)檠芯繉?duì)象,變化高層建筑的高度、高距比及寬度比三個(gè)參數(shù),通過比較平均風(fēng)速比、最大風(fēng)速比、風(fēng)速比變異系數(shù)三者的變化來評(píng)價(jià)住宅小區(qū)周圍人行高度處風(fēng)環(huán)境的變化,得出三個(gè)參數(shù)對(duì)住宅小區(qū)風(fēng)環(huán)境的影響。研究結(jié)果顯示高層建筑高度增大會(huì)引起住宅小區(qū)風(fēng)環(huán)境惡化,當(dāng)高距比小于2時(shí)高層建筑對(duì)住宅小區(qū)風(fēng)環(huán)境影響較小,高層建筑寬度比越大,不同高距比下風(fēng)速比分布的越離散。 研究住宅小區(qū)對(duì)高層建筑周圍人行高度處風(fēng)環(huán)境的影響時(shí),以高層建筑周圍拐角區(qū)域、前面區(qū)域、背面區(qū)域及側(cè)面區(qū)域四個(gè)區(qū)域?yàn)檠芯繉?duì)象,變化高層建筑的高度、住宅小區(qū)的高距比及高層與住宅的寬度之比三個(gè)參數(shù),通過比較平均風(fēng)速比、風(fēng)速比變異系數(shù)及最大風(fēng)速比三者的變化來評(píng)價(jià)高層建筑周圍人行高度處風(fēng)環(huán)境的變化,得出三個(gè)參數(shù)對(duì)高層建筑風(fēng)環(huán)境的影響。研究結(jié)果顯示高層建筑高度增大會(huì)使得高層建筑周圍風(fēng)環(huán)境惡化,高距比在0.52附近時(shí)住宅小區(qū)對(duì)高層建筑周圍人行高度處風(fēng)環(huán)境影響較小。
[Abstract]:Building wind environment mainly includes outdoor wind environment and indoor natural ventilation. Outdoor wind environment is related to pedestrian comfort and even safety. The wind environment has a complex relationship with the shape and size of the building, the relative position of the building and the surrounding landform. In this paper, a series of wind tunnel tests are carried out to simulate and analyze the interaction between the wind environment at the pedestrian height of high-rise buildings and residential areas. In order to study the influence of high-rise building on the wind environment around the pedestrian height of residential area, the paper takes three areas of residential district as the research object, including transverse passage, longitudinal passage and corner area, and changes the height, ratio of height to distance and width ratio of high-rise building. By comparing the average wind speed ratio, the maximum wind speed ratio and the variation coefficient of the wind speed ratio, the changes of the wind environment at the pedestrian height around the residential district were evaluated, and the influence of three parameters on the wind environment of the residential district was obtained. The results show that the higher the height of high-rise building, the worse the wind environment of residential district. When the ratio of height to distance is less than 2, the influence of high-rise building on the wind environment of residential district is small, and the width ratio of high-rise building is larger. The distribution of velocity ratio is more discrete under different ratio of height and distance. When studying the influence of residential district on the wind environment of pedestrian height around high-rise building, four areas, namely corner area, front area, back area and side area, are taken as research objects to change the height of high-rise building. The three parameters of the ratio of height to distance and the ratio of high-rise to residence width are compared to evaluate the change of wind environment in the pedestrian height of high-rise building by comparing the variation of average wind speed ratio, the coefficient of variation of wind speed ratio and the maximum wind speed ratio. The influence of three parameters on the wind environment of high-rise building is obtained. The results show that the increase of the height of high-rise buildings will make the wind environment of high-rise buildings deteriorate, and the impact of residential quarters on the wind environment around the height of high-rise buildings is small when the ratio of height to distance is near 0.52.
