ABSTRACT: Mokattam Plateau, east of Cairo, has been affected by successive rock slope failures. Retreat of the plateau edges caused considerable damages to several buildings and to the main road along the cliff. Mokattam is capped by limestone interbedded with shale that has an detrimental impact on the stability of the steep rock slopes. The present work deals with the assessment of geotechnical hazards in this area. It covered the failure modes, joint patterns, topographic parameters, boundary stresses, landslide features, rockfall mechanism, location and geometry of potential sliding planes and triggering factors. Establishing monitoring and early warning systems, and rehabilitation procedures were suggested to save the endangered structures existed near the retreating cliff. Assessment of the rockfall potential and application of engineering technology designed to prevent movement or to control movement once begun were considered.
RÉSUMÉ: Plateau Mokattam, à l'est du Caire, a été affecté par des défaillances de talus rocheux successifs. Retraite des bords du plateau a causé des dommages considérables à plusieurs bâtiments et de la route principale le long de la falaise. Mokattam est plafonné par interstratifiées de calcaire avec de schiste qui ont une action néfaste sur la stabilité des pentes rocheuses abruptes. Le présent travail traite de l'évaluation des risques géotechniques dans ce domaine. Elle a porté sur les modes de défaillance, les modèles communs, les paramètres topographiques, des contraintes limites, des glissements de terrain, chutes de pierres, mécanisme de l'emplacement et de la géométrie de facteurs plans de glissement et de déclenchement potentiels. Établissement d'une surveillance et des systèmes d'alerte précoce, et les procédures de redressement ont été suggérées pour enregistrer les structures en voie de disparition existait près de la falaise effondrement. Évaluation du potentiel de glissements de terrain et l'application de la technologie d'ingénierie visant à empêcher tout mouvement ou de contrôler le mouvement une fois commencée ont été pris en compte.
