About the Cover

A numerical analysis of the rehabilitation of the DJBEL ELOUAHCH tunnel at the East-West Motorway of Algeria, was carried out following a partial landslide of its left tube, using the PLAXIS 2D calculation code which is based on the finite element method (FEM). The goal is to design a model of this tunnel reinforced with fiberglass bolts and show the excavation influence of the left tube on the right tube during the repair phases; In order to establish a study on the behavior of the latter to enhance the solutions applied in this case. A simplified approach is used to strengthen the tunnel's forehead numerically and replace the bolts and soil / bolt interaction with an equivalent parameter (increase cohesion and friction angle of the soil). In this context, The Iraratna Model [1988, 1990] was used to determined the equivalent geotechnical characteristics of the tunnel to be repaired.
