Abstract

The efficiency of compaction of earth dam’s embankment is influenced by the initial
characteristics of the soils, namely the deformation modulus and density. These two parameters automatically
affect the deformations of the dam which can directly impact on its safety. The modeling of these
deformations is an essential investigation allowing the comprehension of the dam’s behavior. The main
objective of modeling is to analyze the behavior of the dam and compare it with monitoring data. A lot of
difficulties are recorded for the estimation of embankments deformation moduli required for modeling. A
parameterized analysis in relation to the variation of this parameter is necessary for the estimation of earth
dam’s settlement. The present study concerns the parameterized analysis of the correlation between the
parameter influencing compaction, especially deformation modulus, and the deformations of the dam. An
application carried out on the Boughrara dam in the region of Tlemcen in the north-west of Algeria is
presented. The modeling result is compared with the monitoring measurements of dam. This study led to the
verification of the compatibility, for different values of deformation modulus, between the settlement of the
dam by modeling and by monitoring in order to validate the mechanical behavior of the dam.
