Abstract: The current global economy is facing tremendous downward pressure due to the lasting impact of extreme
weather, COVID-19 pandemic, and regional wars. Boosting economic vitality and driving sustained economic growth
via technological innovation and industrial upgrading has become a common choice for major global economies. Digital
transformation and intelligent construction are being vigorously developed in China. Some of the advanced technologies
in the fields of 5G communications, artificial intelligence, and the Internet of Things have been gradually integrated into
the production and management. The overall goals and technical paths of intelligent tunnel construction are presented
and a series of intelligent construction technologies used in shield/TBM and drilling-and-blasting methods are
introduced. Combined with cutting-edge technologies, the main issues and development prospects encountered in
intelligent construction are discussed, thereby providing an outlook. The main conclusions are presented as follows: (1)
The upgrading of tunnel construction from mechanization to intelligence is an inevitable trend. (2) The intelligent
construction of tunnels can be divided into two stages: primary and advanced. Tunnel construction in the primary stage
only realizes intelligent equipment operations in individual scenarios and simple operations. The advanced stage refers to
the realization of the entire process of tunnel construction, multi-scenario, intelligent perception, decision-making,
interconnection, and collaboration. (3) Intelligent prefabricated production line + on-site intelligent assembly + digital
control will become the trend in tunnel construction. (4) Intelligent construction will introduce new vitality into the
tunnel industry and promote industry upgrading.
