Evaluating the Safety and the Effect of Blast Loading on the Shotcrete together with lattice girder Support of Tunnels

Farnoosh Basaligheh, Hamidreza Karimi Tabar, Majid Nikkhah

Damage to tunnels caused by explosions may damage the support structure and the stability. This damage is due to either blasting the working face for drilling progress or an explosion inside the tunnel. The present study investigates the…
