Abstract
Water leakage from a dam is always important, but particularly where the preservation of water is essential in semi-dry areas, such Iran. At Kamal-Saleh Dam, the rock mass rating (RMR) and geological strength index(GSI) systems were used to identify the quality of the rock mass, which is particularly important in a foliated material. The RMR results were compared with Lugeon tests undertaken in vertical and oblique holes along the dam foundation and abutments. Although the rock quality designation values could not be used to indicate the quality of the rock mass, they had a direct relationship with the Lugeon values.
Résumé
Les pertes d’eau depuis un réservoir de barrage sont toujours importantes à considérer, plus particulièrement quand la préservation de la ressource est essentielle dans des régions semi-arides telles que l’Iran. Au barrage de Kamal-Saleh, les systèmes RMR et GSI ont été utilisés pour caractériser le massif rocheux constitué de matériaux foliés. Les résultats RMR ont été comparés avec les essais Lugeon réalisés dans des forages verticaux et obliques le long des fondations et des appuis du barrage. Bien que les valeurs de RQD ne puissent être utilisées pour préciser la qualité du massif rocheux, une relation directe a été établie entre ces valeurs et les valeurs des essais Lugeon.
