缝合城市肌理:北京六环路副中心段入地改造及启示

Mend the Gap:the Transformation of Beijing Sixth Ring Road Sub-center into the Ground and Its Enlightenment

从城市肌理割裂的原因出发,剖析了城市建设过程中由于线性交通工程建设原因造成城市肌理分割的原因。结合高速公路的路堤、路堑、桥梁等不同形态的分析,阐述了高速公路对于城市的影响,进而在缝合城市肌理视角下得到高速公路改造思路,即功能调整、形态调整和景观提升。在理论研究与案例分析基础上,结合北京城市副中心建设中遇到的实际问题,即东六环路对于城市副中心的分割影响,研究其改造方案。六环路改造项目结合前文的理论研究,确定了局部段入地并进行景观提升的改造思路,并分析改造后的预期效果。随着未来城市化的进程,原有高速公路对于城市的分割作用越发明显,改造项目也会越来越多,本文对于其理论的研究和六环路项目的分析可以为同类城市发展区域或同类型道路交通问题提供一些新思路和参考性设计方案。

Starting from the reason of the split of urban texture,in this paper the reason for the split of urban texture caused by the construction of linear transport in the process of urban construction is discussed.Based on the analysis of different forms of highway,such as embankment,cutting,bridge and so on,the influence of expressway on the city is explored,and the reconstruction ideas of expressway are obtained from the perspective of stitching urban texture,which are adjustment of function,of form and improvement of landscape.On the basis of theoretical research and case analysis,starting from a practical problem in the construction of Beijing’s urban sub center,that is,the influence of the East Sixth Ring Road on the division of the urban sub center,and studies its transformation scheme.Combined with the previous theoretical research,the sixth ring road reconstruction project determines the transformation idea of local sections entering the land and improving the landscape,and analyzes the expected effect after the transformation.With the process of urbanization in the future,the original Freeway plays a more and more important role in the division of the city,and there will be more and more reconstruction projects.The theoretical research and the analysis of the Sixth Ring Road Project in this paper can provide some new ideas and reference design schemes for the traffic problems of the same type of urban development area or the same type of road.
