To further improve the construction level of drillingandblasting method for long tunnels in China′s
plateau areas, the current situation of drillingandblasting construction technology in China′s
mountain tunnels is present, and advance geological prediction, mechanized
construction, application of new energy electric equipment, assembly
construction, intelligent construction, carbon emission, and efficient
construction management are introduced. In addition, the important development directions
of carbon emission, construction technology in China′s
mountain tunnel are proposed. Following conclusions are drawn: (1) The research
and application of ultralong horizontal drilling in
advance geological prediction of tunnel should be paid attention to. The
research on multisource geological information
acquisition technology and intelligent fusion interpretation should be
conducted to improve the target acquisition level and prediction accuracy of
tunnel advance geological information. (2) It is necessary to further improve
and refine the relevant standards and industrial specifications for largescale mechanized supporting construction of tunnels, conquer the
core technology of largescale tooling, and realize the
development and application of some key process equipment. (3) For the new
energy electric engineering equipment, it is necessary to further improve its
battery energy storage capacity and realize the intelligent rapid battery
replacement technology in the tunnel. (4) It need to strengthen the research on
specialized lining assembly equipment and related construction organizations
that are limited to uninterrupted traffic in narrow tunnel spaces, it is an
important way to achieve the assembly of tunnel lining using drilling and blasting
methods. (5) The realization stage of intelligent tunnel construction includes:
intelligent equipment and intelligent construction. (6) The theoretical
research and practical application of carbon emissions during tunnel
construction should be strengthened. (7) The realization of efficient
construction management needs to further promote and improve the design and
construction general contracting mode. The construction unit should fully
leverage the autonomy and flexibility of the design and construction units in
dealing with the complex and everchanging environment
of tunnel construction. Construction companies should strengthen the resource
orientation and allocation in the key path and key chain of tunnel construction，and improve the level of grassroots management.
