... 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. RESUME: La methode de convergence Confinement est une methode courante d'analyse de tunnels, qui est...

... for the linearly elastic material is a nonlinear problem because there are more unknowns (Young's modulus, Poisson's ratio, stress) than constitutive equations. On the other hand, most rocks show distinct non-linear deformation behaviour. In direct calculations, there are no difficulties in accounting for known...
