【摘要】：隨著中國(guó)城市化進(jìn)程的飛速發(fā)展,城市人口的快速激增,土地資源的日益匱乏,如何有效解決人口與土地的緊張關(guān)系已成為一個(gè)重要的城市問(wèn)題。居住區(qū)作為一種常見(jiàn)的建筑類型在整個(gè)城市建筑總量當(dāng)中占有相當(dāng)大的比重,對(duì)城市土地資源的需求量也是所有建筑類型之中最多的一種,通過(guò)提高住區(qū)高度和容積率的方式來(lái)節(jié)約土地資源成為了一種有效的解決方式。 在住區(qū)高度和容積率指標(biāo)不斷提升的因素影響下,新的矛盾開(kāi)始顯現(xiàn)：高密度的居住環(huán)境難以保證充足的日照采光和良好的自然通風(fēng),其中日照作為國(guó)家強(qiáng)制性標(biāo)準(zhǔn)于2002年開(kāi)始實(shí)行。但是規(guī)劃部門提出的住宅用地規(guī)劃設(shè)計(jì)條件中容積率的設(shè)定往往通過(guò)經(jīng)驗(yàn)值的提取,缺乏明確依據(jù)。在實(shí)際項(xiàng)目中往往出現(xiàn)日照標(biāo)準(zhǔn)與容積率指標(biāo)無(wú)法兼顧的矛盾。 研究階段,通過(guò)對(duì)南京河西地區(qū)數(shù)個(gè)高層住區(qū)實(shí)例的調(diào)查分析,對(duì)高層的用地面積、容積率、層數(shù)和戶型單元和總體組織形態(tài)等特點(diǎn)進(jìn)行歸納,并對(duì)住宅單體與組合的理論模型進(jìn)行日照分析及計(jì)算,求解住宅形體與日照間距的量化關(guān)系,并提出基于現(xiàn)行日照標(biāo)準(zhǔn)的高密度排布方法。 設(shè)計(jì)階段,通過(guò)南京河西低碳生態(tài)城E-3-5地塊為載體進(jìn)行城市設(shè)計(jì)及單體設(shè)計(jì),根據(jù)上一階段的研究結(jié)果直接參與總體規(guī)劃設(shè)計(jì),并確定合適的容積率指標(biāo),利用CFD軟件對(duì)形體進(jìn)行風(fēng)環(huán)境優(yōu)化,在此基礎(chǔ)上,再在建筑層面對(duì)總體規(guī)劃進(jìn)行深化設(shè)計(jì),得到一套日照環(huán)境和風(fēng)環(huán)境向好的設(shè)計(jì)方案。 本文的研究與設(shè)計(jì)過(guò)程利用計(jì)算機(jī)軟件模擬技術(shù),通過(guò)量化日照環(huán)境、風(fēng)環(huán)境等手段,提出住宅形體與日照間距的量化關(guān)系,提出居住用地的容積率估算的可行性和具體操作方法,為高層高密度住區(qū)的設(shè)計(jì)方法提供一定的借鑒意義。
[Abstract]:With the rapid development of urbanization in China, the rapid increase of urban population and the scarcity of land resources, How to effectively solve the tension between population and land has become an important urban problem. As a common type of building, residential area occupies a large proportion of the total amount of urban buildings. The demand for urban land resources is also one of the most of all architectural types. It has become an effective solution to save land resources by increasing the height and volume ratio of residential areas. Under the influence of the increasing index of residential height and volume ratio, new contradictions are emerging: it is difficult to ensure adequate sunshine and good natural ventilation in a high-density living environment. Among them, Rizhao was put into practice as a compulsory national standard in 2002. However, the setting of volume ratio in the planning and design conditions of residential land proposed by the planning department is often carried out through the extraction of empirical values. Lack of clear basis. In the actual project, there is often a contradiction between sunshine standard and volume ratio index. In the research stage, through the investigation and analysis of several high-rise residential areas in Hexi area of Nanjing, the characteristics of the land area, the volume ratio, the number of floors, the household type units and the overall organizational form of the high-rise buildings are summarized. The theoretical model of house unit and combination is analyzed and calculated, and the quantitative relationship between residential body and sunshine distance is solved, and a high-density arrangement method based on current sunshine standard is proposed. In the design stage, the urban design and monomer design are carried out through the E-3-5 plot of Hexi ecological city in Nanjing. According to the results of the previous stage, it is directly involved in the overall planning and design, and the appropriate volume ratio index is determined. The wind environment is optimized by using CFD software. On this basis, the overall planning is further designed at the architectural level, and a set of design scheme for sunshine environment and wind environment is obtained. The research and design process of this paper uses computer software simulation technology, through quantifying sunshine environment, wind environment and other means, puts forward the quantitative relationship between residential body and sunshine distance. This paper puts forward the feasibility and concrete operation method of estimating the volume ratio of residential land, which provides a certain reference for the design method of high-rise and high-density residential area.
