... the determination of two curves. One of them is the ground reaction curve (GRC), which represents the load or reaction exerted on the walls of the tunnel in order to detain its radial displacement. Many authors have developed expressions for the GRC under different rockmass behavior hypotheses. Among others, we can...

... for use it as monitoring variable to assess tunnel stability. It has obtained an analytical expression useful to obtain the diametric deformation from tape extensometer convergence measures. A procedure to analyze the diametric deformation is proposed. A practical example is carried out. 1 INTRODUCTION...
