Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishThe paper synthetically deals with the procedures frequently used to assess the opening convergence, to design the temporary lining, to evaluate the stress and displacement that are characteristics of the achieved equilibrium state. The stiffness of the lining, in its actual shape and not with the usual closed ring modeling, is evaluated; settling lining supports are taken into account as well as differentiated and evolving stresses in the bolts. The results obtained by an extensive parametric study allow the pointing out of some remarks and comparisons.
