Resumen:

A criterion proposed by Instituto de Ingenieria, UNAM (II-UNAM) to perform ground-lining interaction analyses for tunnels, when these are formed by segmented rings and double lining, is described. The criterion can be introduced in the ``hybrid'' analysis method, which is an iterative procedure between geotechnical and structural numerical modeling, where the convergence in terms of diametrical displacements between both types of modeling allows determining the effective stiffness of the tunnel [1]. The criterion allows calculating loads and mechanical elements for the tunnel lining and checking serviceability limits corresponding to constructive or operative aspects. It is useful in the design stages, for revisions of tunnels that are under construction or for existing tunnels affected by new engineering works. In this paper, it is applied to check the interference of a new deep foundation with an existing tunnel.
