Abstract: Green, efficient, and intelligent construction is a recent important developmental trend of infrastructure construction in China. Based on the analysis of the construction status of Chinese underground metro stations, the technical path to realize the green, the efficient, and the intelligent construction of underground metro stations is stated as follows. (1) A systematic design theory and the technical system of new structural types represented by prefabricated underground metro stations with prefabricated dualpurpose concrete wall should be established, and the development and the application of new functional materials must be promoted. (2) The intelligent construction of the underground metro station can be realized from five aspects, which include materialstructure integrated collaborative design, lightweight BIM platform and integrated application, intelligent fusion perception based on engineering Internet of Things, intelligent construction machinery and supporting technology, and lifecycle intelligent security control platform based on big data. (3) The green construction of the underground metro stations is realized through the ground source heat pump technology, phase change energy storage technology, resource utilization of residual sludge, and waste concrete. As per the above breakthroughs in a series of key techniques, the construction of the underground metro stations in China will be promoted to the international leading level, while the new direction of green, efficient, and intelligent construction in urban underground space development will be led.
