The authors review twenty years of geotechnical investigations of Na'ur Landslide No. 4. The landslide is considered as one of the most important landslides along the road between Amman-Na'ur and the Dead Sea.

Hydrology, geomorphology, geology, and geotechnical studies of the landslide were reviewed in some details to understand the main reasons for the movement. Previous geotechnical studies at this site were also summarized and briefly discussed.

To stabilize the slide in order to built the road requires excavating weak material and reconstructing an embankment founded on strong bedrock. A stability analysis for this solution allows comparison of the as-built road and the recommended solution.

The main conclusions are that drainage is necessary, the upper slope above the embankment should be flattened, the reconstruction of a road through the slide is feasible, and the present road will have continuous sliding problems in the future.

Revue de vingt années d'études géotechniques du glissement de terrain de Na'ur en Jordanie

Résumé

Les auteurs passent en revue vingt années d'études géotechniques rélisées sur le glissement de terrain de Na'ur qui est considéré comme l'un des plus importants le long de la route entre Amman-Na'ur et la Mer Morte.

Les études hydrogéologiques, géomorphologiques, géologiques et géotechniques sont évoquées de façon détaillée afin de comprendre les principales raisons de ce glissement.

Pour stabiliser le glissement et faire passer la route, il est nécessaire d'enlever le matériau désorganisé et de reconstruire un remblai fondé sur le substratum. Une étude de stabilité permet de comparer la solution recommandée à la route acutelle.

Les principales conclusions sont que le drainage est nécessaire, qu'il faut aplanir la pente au-dessus du remblai, que la reconstruction de la route en traversant le glissement est possible et que la route actuelle continuera à être affectée en permanence par les glissements.
