Recent progress in convergence confinement method

Résumé

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 problems, is proposed to remove such drawback in a self governing way. The methodology has been set up from analyses on direct calculations on a simplified reference three dimensional tunnel problem.
