Large Deformation Control and Structural Optimization of Tunnels in Shallow Fractured and Expansive Formations Based on Discrete Element Simulation

Tunnel construction in shallow-buried fractured and swelling schistose rock formations is highly prone to large structural deformation issues. Taking the context of a tunnel located on the Xi’an–Ankang high-speed railway as background, thorough investigations were conducted into the arch crown subsidence, horizontal co...
