Clay core rock-fill (CCR) dams are chosen dam
construction model due to their low cost and rapid construction advantages. The
stability of dam embankment and analyzing their earthquake resistance is of
great concern to geotechnical engineers. Here, we analyze static and dynamic
degrading behavior of a clay core rock-fill (CCR) dam through using the finite
element method. The static part of the analysis considers the stage
construction, reservoir impoundment and total displacements while, the dynamic
part considers the seismic response of the dam under a real earthquake data
which the data corresponds to typical measures of a peak ground acceleration
(PGA). The static state analyses show a gradual increase in the magnitude of
vertical displacements during the impounding stage where the hydrostatic force
acts on the surface of the dam body and causes additional force on the clay
core section. When the dam is subjected to real earthquake data which had a 0.4
g PGA, we observe larger displacement values compared to the static phase.
