This guideline will be contained by first time into the Seismic Design Chapter of the seismic design handbook of CFE. The seismic recommendation for tunnels will be fundamentally oriented to evaluate the deformations in both directions: longitudinal axis (axial and curvature) and transverse axis (ovaling). These seismic recommendations were adapted to the new criteria of the seismic hazard of Mexico, where the acceleration and the proposed design spectra are continuums within the Mexican territory. The seismic design criteria to analyze the tunnels’ longitudinal direction are based on the solution of free field theory. Whereas the solution for analyzing the tunnels’ transverse direction, it is considered the plane strains state; in order to carry out these analyses, an equations to evaluate the strain to determining bending and the axial force are used, later both are compared with a maximum permissible strain. In the same way, an abacus of practical and simple use is proposed to determine if the tunnel expires, based with the criterion of unitary transverse strain before dynamic solicitations, knowing only the elastic properties of the rock and the lining material. In spite of the little information that exists on seismic effects in tunnels, these recommendations will try to cover the concepts that must be checked and the parameters that must be using in the tunnels’ seismic design.
