Numerical modeling of the pathological case of a damaged tunnel application to Djebel El-Ouahch tunnel (east–west highway)
Abstract This work deals with a numerical analysis of a pathological case of a part of tunnel T1 of Djebel El-Ouahch which suffered a collapse. The pathological analysis of state of stress and state of deformation in the soil and in the tunnel wall was examined. Numerical modeling is performed in 3D space using the PLAXIS 3D TUNNEL calculation code which is based on the finite element method; the behavior of the soil is described by the elastoplastic model of Mohr–Coulomb. The results are presented in terms of settlement at ground free surface, vertical displacement under the tunnel floor, stresses, and deformations developed at the tunnel retaining level and in the ground around retaining to be able to analyze the causes of the collapse.
