Application du calcul à la rupture à la stabilité du front de taille d’un tunnel

Abstract

Frant stability must be examined priar ta tunnel canstructian in arder ta ensure gaad safety canditians while baring it. When the tunnel is at shallaw depth and is driven using a baring machine with full face suppart, three laading effects need ta be cansidered: influence af the sail weight, sail surface laads, retaining pressure at the frant.
