Carbon Emission Characteristics of Inclined Shaft Construction in Highway Tunnel

Abstract

Although the existing studies have conducted a lot of analysis on the carbon emission characteristics of the main tube of the tunnel (Ahn et al. in Construction research congress 2010: innovation for reshaping construction practice—proceedings of the 2010 construction research congress, 2010; Li et al. in Mod Tunn Technol 52:1–7, 2015; Li et al. in ISWREP 2011—Proceedings of 2011 international symposium on water resource and environmental protection, 2011), there are few literature reports on the carbon emission characteristics of the inclined shaft of the tunnel. The inclined shaft is an important auxiliary tunnel for the construction of a long tunnel, which plays an important role in shortening the construction period of the project and speeding up the construction progress. Relying on engineering cases, this project analyzes the carbon emission characteristics during the construction of inclined shafts of highway tunnels, clarifies the carbon emission levels during the different construction processes, and explores the influence law of inclined shaft slope and length on the carbon emissions during excavation and slagging.
