SUPPORT FOR LONG TUNNELS YESTERDAY AND TODAY

SOUTENEMENT DES TUNNELS PROFONDS AUTREFOIS ET AUJOURD'HUI

The authors use the studies on the stability of rail tunnels built at various times as a basis for examining the pattern of stress-deformation graphs to define the behaviour of various types of support and they reach the following conclusions: for schists, the resistance limit is attained at little depth, mechanised methods of fixing supports rapidly help during the period leading up to stability, the "new Austrian Method" can take various forms.
