摘要:The development and utilization of underground space is an effective way to solve the shortage of urban space capacity. It is also an inevitable choice for the sustainable development of urban underground space. The development and utilization of underground space in small and medium-sized cities in China started relatively late and lacked practical basis. This paper selects three representative small and medium-sized cities in east China to study the status quo, contents and achievements of underground space development and utilization, makes a comparative analysis, and puts forward the overall characteristics of underground space development and utilization in small and medium-sized cities, hoping to provide reference for the development and utilization of underground space in small and medium-sized cities in the future.
