Preliminary Exploration of the Overall Control Mode of Urban Underground Space in the Context of Park Cities

The orderly development, planning and construction of underground space is an objective requirement for enhancing the safety and resilience of urban development. This paper first elaborates on five dimensions of urban underground space construction in the context of park cities: safety and resilience, quality of life, green and low-carbon, intelligence and smartness, and modern governance. The issues faced in the full-cycle development of domestic underground space due to the vast project scale and long construction period are summarized, which respond to the diverse needs of the park city concept. These issues are summarized as horizontal technological fragmentation and vertical transmission disconnection. Based on this, four stages of the master control mode for urban underground space construction are proposed, namely, "objective analysis and judgment-planning to deepen-design collaboration-digital and intelligent construction." Combined with practical application cases of the master control mode in underground projects, the paper illustrates the specific implementation pathways for achieving safe and sustainable development in park cities through full-lifecycle management processes.
