Research on Planning Model of Urban Deep Underground Space Based on Application Scenario

The development and utilization of underground space is an important way to solve many urban problems in China, such as land resource scarcity, dense population, and traffic congestion. However, the current shallow underground space development and utilization methods are difficult to cope with the complex deep land development scenarios in China. Exploring the organizational model of deep land space development is an inevitable need for China’s urbanization development in the new era. This article reviews the application scenarios of deep underground space at home and abroad, analyzes the corresponding spatial characteristics and usage needs in various scenarios such as deep mines, deep transportation, deep storage, and deep laboratories through case studies, summarizes and proposes four typical deep underground space network organization modes: point, line, surface, and three-dimensional network. The applicable characteristics and possible application scenarios of the four typical development modes are analyzed, in order to provide reference and reference for the development, construction, and scene design of deep underground space in China.
