Original Paper


As is well known, in order to select remediation measures to correct or prevent slope instabilities, it is essential to identify and characterize the instability mechanisms. This task is especially complex for heterogeneous rock masses such as Flysch formations. This paper addresses the assessment of corrective measures used in carbonate Flysch formations by classifying and grouping field data reported in an available database in order to associate this data with various instability mechanisms and stratigraphic column types as well as with the corrective measures taken to stabilise them. For this purpose, 194 slopes have been geomechanically characterized, mainly by considering the observed instability mechanisms. The corrective measures that were applied have been evaluated for their suitability and performance, and, if applicable, the causes of their malfunction have been also studied. As a result, some guidelines based on the observed behaviour and the suitability of the correction measure as a function of instability type are proposed for similar slopes.

Comme il est bien connu, dans le but de sélectionner les mesures correctives pour corriger ou prévenir des instabilités de pente, il est essentiel d’identifier et de caractériser les mécanismes d’instabilité. Cette tâche est d’autant plus complexe pour les masses rocheuses hétérogènes telles que des formations de Flysch. Cet article traite de l’évaluation des mesures correctives utilisées dans les formations du Flysch carbonatée, en classant et groupement des données de terrain figurant dans une base de données disponible, afin d’associer ces données avec les différents mécanismes d’instabilité et les colonnes stratigraphiques type, ainsi que des mesures correctrices prises pour les stabiliser. A cet effet, 194 pentes ont été geomécaniquement caractérisées, principalement en examinant les mécanismes d’instabilité observées. Les mesures correctives qui ont été mis en œuvre ont été évaluées pour leur pertinence, la performance et, le cas échéant, les causes de leur dysfonctionnement. En conséquence, certaines lignes directrices fondées sur le comportement observé et l’adéquation de la mesure de correction en fonction du type de l’instabilité sont proposées pour des pentes similaires.
