To promote China′s Carbon Peaking and
Neutralization Policy, provide data support for energy conservation and
emission reduction of metro projects, and address the complex and cumbersome
problem of greenhouse gas quantification process in the construction stage of
metro deep foundation pit engineering, a modular calculation method for carbon
emissions in the construction stage of metro foundation pit engineering is
established based on the whole life cycle theory. Due to the fact that the
metro foundation pits are temporary, the carbon emission calculation process is
divided into three stages: upstream material production, foundation pit site
construction, and material transportation. Furthermore, the greenhouse gas
emissions during construction process of the 02B foundation pit and the pit in
pit of the Beijing City SubCentral station
comprehensive transportation hub project are calculated and analyzed. The
results show that: (1) The CO2 emitted during the
construction stage of 02B foundation pit and the pit in pit reached 20 498.50 t
and 32 422.50 t, respectively. (2) The carbon emission in the construction
stage of the metro deep foundation pit project is related to the construction
method and support strength of the metro deep foundation pit.
