A dam is one of the oldest and largest buildings in the world. This structure is usually constructed to intercept flows, store water, and produce energy. Dams' foundations should really be rocky and robust enough to preserve their rigidity. Despite the great benefits of these structures, they are exposed to the risk of collapse. Two basic problems can confront a gravity dam; the first one is the uplift pressure load that could raise the danger of reversing the dam. The second one is the ground water flow, which can lift the soil under dam. Moreover, cracks are commonly formed in dams after construction. These cracks might produce several complications in the dam structure. Several investigations have shown the influence of the injected veil that made the dams stronger. This study shows the numerical results of the injection influence on a gravity dam. Finite element software is used to check up the best location of the injected veil and the maximum favorable depth. The obtained numerical results show the major effect of the veil injection on the uplift pressure force, the ground water values, and the flows pass under the gravity dam. HIGHLIGHTS The impact of this research can be summed up in these points.; Highlight on one of the major problems that affect the stability of gravity dam.; Clarify how to solve this problem and prevent the losses in different levels (Humans life and economic way).; Illustrate in an easy numerical method how to solve such severe problem.; Encourage the researchers to use the veil injection system in other dam types.; |
