与高密度街区融合的超高层建筑综合体设计策略

DESIGN STRATEGIES OF SUPER-HIGH-RISE BUILDING COMPLEXES INTEGRATED WITH HIGH-DENSITY BLOCKS

城市高密度开发不等同于单纯的高容积率开发,超高层建筑综合体也非简单的功能空间叠加。在小街区、密路网的规划理念指引下,超高层建筑在总体布局、交通组织和功能布局等方面受到不同程度的制约和影响,需通过建筑设计层面的策略和措施,以实现超高层建筑与城市高密度街区的深度融合。为此,着重从多维交通组织、空间立体整合两方面入手,提出步行系统与商业动线相结合、地块间机动车出入口共享、营造开放的城市公共空间、整合地下空间边界高度等设计策略。通过超高层建筑综合体内部与外部、地上与地下系统的设计整合,以高密度促进高效率,构建“根植”于高密度街区上的“垂直城市”。

Urban high-density development is not equal to high volume-ratio development,super high-rise building complexes are not simply a function of space superposition.Under the guidance of planning concept of“small blocks,dense road network”,the overall layout,traffic organization and functional layout of super high-rise buildings are restricted and influenced,strategies and measures of architectural design are needed to achieve the deep integration of super high-rise buildings and urban high-density blocks.From the points of multidimensional traffic organization and 3D spatial integration,some design strategies were put forward,such as the combination of pedestrian system and commercial moving line,the sharing of motor vehicle entrances and exits,the creation of open urban public spaces,and the integration of underground space boundary height.Planning and integrating the interior and exterior of the super high-rise building complex as well as the ground and underground system,it was wanted to promote efficiency in high density blocks to build a“vertical city”under high-density blocks.
