Support Characteristic of a Novel Type of Support in Loess Tunnels Using the Convergence–Confinement Method
TLDR
The convergence-confinement method (CCM) as discussed by the authors is a widely used tunnel design method that can intuitively reflect the interaction between the surroundings and the support structure of the tunnel.Abstract:
