【摘要】：本文在對(duì)高層建筑與風(fēng)環(huán)境相互影響的分析基礎(chǔ)上,提出優(yōu)化高層形態(tài)及風(fēng)環(huán)境的策略,并根據(jù)研究綠色建筑評(píng)價(jià)標(biāo)準(zhǔn),提出適應(yīng)風(fēng)環(huán)境的高層建筑的評(píng)價(jià)標(biāo)準(zhǔn),對(duì)高層風(fēng)環(huán)境優(yōu)化策略的可行性加以驗(yàn)證。高層建筑因其高度和巨大的體量,會(huì)嚴(yán)重阻擋基地內(nèi)風(fēng)向的流動(dòng),當(dāng)風(fēng)撞擊到高層建筑上時(shí),在附近形成了不同類型的氣流,這些氣流相互作用,導(dǎo)致了高層附近風(fēng)環(huán)境復(fù)雜紊亂。高層風(fēng)對(duì)內(nèi)對(duì)外都有巨大的影響:對(duì)外,高層風(fēng)影響城市街道行人的舒適性、市民廣場(chǎng)等室外場(chǎng)地的正�；顒�(dòng);對(duì)內(nèi),由于高層的區(qū)域氣流過(guò)大,導(dǎo)致高層封閉性較高,很難實(shí)現(xiàn)自然通風(fēng),影響使用者的健康和情緒;同時(shí),高層風(fēng)對(duì)高層建筑產(chǎn)生的風(fēng)荷載也是對(duì)結(jié)構(gòu)提出的一個(gè)大挑戰(zhàn)。然而,高層建筑風(fēng)環(huán)境的狀況與高層建筑的形體密切相關(guān),改變建筑的形體可以達(dá)到優(yōu)化風(fēng)環(huán)境的目的。從而實(shí)現(xiàn)在高密度的狀態(tài)下創(chuàng)造舒適性的人居環(huán)境,同時(shí)降低建筑空調(diào)使用能耗,降低高層建筑對(duì)城市環(huán)境的影響。目前關(guān)于高層建筑與風(fēng)環(huán)境的研究尚不完善,所以筆者在本文的研究中先在傳統(tǒng)的高層建筑設(shè)計(jì)基礎(chǔ)上,對(duì)建筑平面、立面、轉(zhuǎn)角處進(jìn)行一定處理,達(dá)到優(yōu)化風(fēng)環(huán)境的目的。隨著非線性設(shè)計(jì)理念的出現(xiàn),風(fēng)環(huán)境的優(yōu)化方法得到了拓展,很多設(shè)計(jì)者從設(shè)計(jì)之初就將風(fēng)做為重要影響因素,“生成”適應(yīng)風(fēng)環(huán)境的形體。為了確定優(yōu)化策略在實(shí)際工程中的可實(shí)施性,需要科學(xué)的、量化的標(biāo)準(zhǔn)去對(duì)優(yōu)化的結(jié)果進(jìn)行評(píng)價(jià)。依據(jù)綠色建筑評(píng)價(jià)體系,可以提取總結(jié)出風(fēng)環(huán)境的評(píng)價(jià)體系,以此檢驗(yàn)建筑設(shè)計(jì)過(guò)程中及實(shí)際運(yùn)行中的風(fēng)環(huán)境狀況,并在后續(xù)使用中不斷進(jìn)行修正,形成越來(lái)越完善的評(píng)價(jià)方法,進(jìn)而不斷指導(dǎo)風(fēng)環(huán)境優(yōu)化設(shè)計(jì)。
[Abstract]:Based on the analysis of the interaction between high-rise building and wind environment, this paper puts forward the strategy of optimizing high-rise building form and wind environment, and puts forward the evaluation standard of high-rise building adapting to wind environment according to the study of evaluation standard of green building. The feasibility of wind environment optimization strategy is verified. Tall buildings, because of their height and huge volume, can seriously block the flow of wind direction in the base. When the wind hits the high-rise building, different types of airflow are formed in the vicinity, which interact with each other. The wind environment near the high level is complicated and disordered. High-rise wind has a great impact on both inside and outside: external, high-level wind affects the comfort of pedestrians on urban streets, public square and other outdoor venues of normal activities; At home, because of the high air flow in the high-rise area, it is difficult to realize natural ventilation and affect the health and emotion of the users. At the same time, the wind load caused by the high-rise wind on the high-rise building is also a great challenge to the structure. However, the wind environment of high-rise buildings is closely related to the shape of high-rise buildings, and changing the shape of buildings can achieve the purpose of optimizing wind environment. In order to create a comfortable living environment, reduce the energy consumption of building air conditioning, and reduce the impact of high-rise buildings on the urban environment. At present, the research on high-rise building and wind environment is not perfect, so the author first deals with the plane, elevation and corner of the building on the basis of the traditional high-rise building design in order to optimize the wind environment. With the appearance of the idea of nonlinear design, the method of wind environment optimization has been expanded. Many designers have taken the wind as an important factor from the beginning of the design to "generate" the shape to adapt to the wind environment. In order to determine the feasibility of optimization strategy in practical engineering, scientific and quantitative criteria are needed to evaluate the results of optimization. According to the evaluation system of green building, the evaluation system of wind environment can be extracted and summarized, which can be used to test the wind environment condition in the course of architectural design and in actual operation, and to revise continuously in subsequent use. Form a more and more perfect evaluation method, and then continue to guide the wind environment optimization design.
