Currently, the progressive use of urban underground space to solve various urban problems is gradually expanding. The development of large-depth transport infrastructure, supported by recent advances in excavation technology, is accelerating this trend. The undergrounde large-scale transportation facility can solve the complex traffic situation in urban centres, and the distribution of overcrowded urban space and floating population underground can preserve a comfortable surface environment. At the same time, new development space can be created in the existing urban space, and highly efficient compressed urban development can be achieved by making advanced use of land and reducing compensation costs. Overseas, urban underground space utilisation projects have been carried out in various fields in specific ways since the mid-1900s. In recent years, Asian countries that lack available land have been actively promoting plans to utilise underground space. For planned and efficient development, laws on underground space development are being enacted and appropriate masterplans are being prepared to create conditions for underground space development. This review examines the underground space projects and policies underway in Asian countries such as Hong Kong, Singapore, Japan, and China, as well as in North America and Europe, and explores how to create large-depth underground space development. It also provides a comparative analysis of domestic policies and research on large deep underground space development and actual planning cases to contribute to the establishment of optimal planning directions for the creation of future underground urban spaces.
