... Abstract: The Convergence Confinement Method (CCM) is a 2D simplified approach for resolving 3D rock-support interaction problems associated with the installation of support near a tunnel face in underground excavations. Some authors have recently put forward the idea that the behaviour...

... ABSTRACT: The convergence-confinement method is a tool that enables us to give an appreciation of the nature of the interplay between the rock-mass and the support, and the effect of the variation in the properties of the rock on the support load. From a theoretical scope, the approach...

... ABSTRACT: Convergence Confinement method is a plane strain approximation of supported tunnel annalysis which is currently used in practice. However, efficiency of this method suffers from undetermination of the instant of support activation. A new approach including three dimensional tunnel...
