Resume

Le tunnel de l’Alb traverse, sur 9 km environ, des sédiments argileux jurassiques à stratification horizontale; ils sont peu diaclasés et l’on peut négliger cette propriété dans les problèmes de mécanique des roches. Ainsi, des essais très coûteux grandeur nature peuvent être remplacés par des essais de laboratoire et, jusqu’à un certain point, par des essais in situ.

Abstract

The Alb tunnel crosses, for a distance of approximatively 9 km, horizontally layered clayey sediments of jurassic age; the jointing is scarce, so it can be neglected in problems of rock mechanics. Thus very costly full-scale tests can be replaced by laboratory tests and, to a certain extent, by in-situ tests.
