Abstract
In this study, elastic analyses are carried out to investigate the effects of different rock joint inclinations (0°, 30°, 60°, 90°) and spacings (1 m, 4 m and 5 m) on the elastic behavior of the concrete gravity dam under static loading condition. Discrete element simulations are performed using UDEC (1993) for two specific static load combinations (LC-A and LC-B) as per Indian Standard: 6512 (1984). The orientations of the single joints in the rock masses are found to play vital roles regarding stress generation within the dam body. From the results, the magnitude of principal stresses is found to increase as the spacing between the joints decreases for all the rock foundations. The principal stresses are found higher in magnitude at heel of the dam than the toe under load combination A. However, for load combination B, the zone of stress concentration is observed to be more at toe than heel of the dam.
