To realize the complete life cycle of railway tunnel
in green and lowcarbon development, a case study is conducted on the Qinghuayuan
tunnel, the New Badaling tunnel, and the Badaling Great Wall station, data
statistical analysis is conducted to assess the railway tunnel construction and
operation stage of carbon emissions. The authors propose tunnel carbon
reduction design strategy from the aspects of tunnel line, station selection,
construction, structure, ventilation, and lighting. Research results show that
the carbon reduction design strategy mainly involves increasing carbon sink and
reducing carbon emission. Carbon sink can be increased by (1) reducing the
surface land occupation and increasing the surface green area; (2) adopting
green retaining wall and green vegetation cover for the tunnel entrance to
increase the carbon sink capacity. Carbon emission can be reduced by (1)
reasonably selecting tunnel line and station to minimize passenger traffic
connection; (2) reducing the amount of earthwork excavation and support
measures using the station tunnel design scheme; (3) designing concept and
method of surrounding rock selfbearing tunnel to reduce
the amount of lining concrete; (4) adopting airfree
piston ventilation system, intelligent management of lighting system, elevator,
and other large equipment for the underground station to reduce the energy
consumption in the operation stage. Finally, the future green construction
technologies of railways, such as the construction of green structures, the
research and development of fully prefabricated and exquisite structures, the
intelligent management and control technology of equipment, the railway strip
photovoltaic power plant, and the compressed air energy storage power station,
are proposed.
