Study on Mechanical Properties of Shotcrete Arch Frames in Tunnel Engineering Considering Blasting Excavation Effect at Early Age

Steel arches and shotcrete systems are the most commonly used forms of initial support structures in underground tunnel engineering. Blasting and excavating in tunnels constructed using the drill-and-blast method affect the synergy between the early-age concrete and the steel arch. Research on the p...
