résumé This paper concerns a study o the interaction between tunneling in soft soils and adjacent structures. Analysis is performed using a full three-dimensional finite model, wich takes into consideration he presence of the structure during the construction of the tunnel. The soil behavior is assumed to be governed by an elastic perfectly-plastic constitutive relation based on the Mohr-Coulomb criterion with a non-associative flow rule. The paper is composed of three parts. The first part describes the numerical model used in this study, the second part concerns a full three-dimensional analysis of the construction of a shallow tunnel close to a two level building. The last part includes comparison between the full 3D analysis and a simplified approach, wich neglects the influence of the presence of the sructure in the determination of the tunneling-induced ground movement.
