The tunnels and urban underground projects have been a
key part of infrastructure construction in China, and gradually develop toward
deeper, larger, and longer. Complex geological conditions, as well as high
ground stress, high ground temperature, high gas content, high water pressure,
and other harsh operating conditions, are inevitably encountered during
construction and efforts have been made to solve the problems of great
construction difficulties, low efficiency, and frequent accidents. Based on the
current situation of underground space development technology and equipment in
China, the problems faced in this field are summarized. The development
direction of tunnel and underground engineering construction and equipment in
China is proposed. In order to cope with these problems, relevant suggestions
are put forward: issue some policy documents on the demonstration and
application of new tunnel construction equipment to promote technological
innovation; rationally develop and utilize underground space, promote green
construction and contribute to the carbon peak and neutrality target; develop
intelligent technology for shield machines, so as to realize green operation
and less manned or manless operation; accelerate the research on key
technologies and major equipment to solve the bottleneck problems, developing
new construction method and equipment for tunnel construction under complex
geological environment and extreme working conditions, key technologies and
major equipment for urban underground engineering.
