| Popis: | The efficiency of compaction of earth dam’s embankment is influenced by the initialcharacteristics of the soils, namely the deformation modulus and density. These two parameters automaticallyaffect the deformations of the dam which can directly impact on its safety. The modeling of thesedeformations is an essential investigation allowing the comprehension of the dam’s behavior. The mainobjective of modeling is to analyze the behavior of the dam and compare it with monitoring data. A lot ofdifficulties are recorded for the estimation of embankments deformation moduli required for modeling. Aparameterized analysis in relation to the variation of this parameter is necessary for the estimation of earthdam’s settlement. The present study concerns the parameterized analysis of the correlation between theparameter influencing compaction, especially deformation modulus, and the deformations of the dam. Anapplication carried out on the Boughrara dam in the region of Tlemcen in the north-west of Algeria ispresented. The modeling result is compared with the monitoring measurements of dam. This study led to theverification of the compatibility, for different values of deformation modulus, between the settlement of thedam by modeling and by monitoring in order to validate the mechanical behavior of the dam. |
