Abstract: Similar to the methods used to evaluate transverse reactions, longitudinal responses of tunnels are also evaluated using simplified analytical models and more complex numerical models, depending on the complexity of the soil-structure system, the level of seismic action and the responsibility of the structure. The following sections discuss a simplified method that assumes that the tunnel deformations correspond to the free field deformations and that the tunnel does not affect the soil deformations. A more refined method takes into account the interaction of the structure with the soil, for which a beam model on an elastic foundation is used.
Key words: Differential equation, deformation, soil, structures, model, structure, tunnel, pressure, elastic medium, technique.
