... and reinforcement is most efficient are key issues in underground tunneling. The convergence-confinement method (CCM) is a procedure that enables one to estimate the load imposed on a support and reinforcement system installed behind the face of a tunnel. When the support is installed close to the tunnel face...

Paper presented at the ISRM International Symposium - 2nd Asian Rock Mechanics Symposium, September 11–14, 2001
Paper Number: ISRM-ARMS2-2001-064
... ABSTRACT: The convergence-confinement method is one approach to the analysis of ground-support interaction. The conventional plane strain convergence curve cannot consider the 3-D arching effect occurring ahead of the face and the fast stress reduction in the unsupported section. The final...
