Abstract.

The design of tunnels and slopes in heterogeneous rock masses such as flysch presents a major challenge to geologists and engineers. The complex structure of these materials, resulting from their depositional and tectonic history, means that they cannot easily be classified in terms of widely used rock mass classification systems. A methodology for estimating the Geological Strength Index and the rock mass properties for these geological formations is presented in this paper.

Résumé.

L'étude des tunnels et des talus dans des masses rocheuses hétérogènes, telles que le flysch, représente un défi majeur pour les géologues et les ingénieurs. La complexité de ces formations, résultat de leur histoire de sédimentation et de leur mise en place tectonique, pose des problèmes pour leur classification par des systèmes reconnus de classifications géotechniques. Dans ce travail une méthodologie pour l'estimation du GSI (Geological Strength Index) et l'évaluation des propriétés des masses rocheuses de flysch est présentée.
