Özet
Flow through dams has been extensively studied using numerical models in hydraulic
engineering. And the present studies the numerical modelling of flow through an
embankment using Plaxis software under dynamic loads such as earthquakes in dynamic
phase with HS small parameter in undrained stage and initial phase or static phase with Mohrcoulomb parameter in the drained stage. In any phase we used different material model such
as Mohr- coulomb, linear elastic, and Hs small . Furthermore, it should be emphasized that
this study incorporates published analytical findings as part of its numerical methodology.
The objective is to observe the effects on settlement, acceleration, lateral displacement, and
excess pore pressure. And finally, according to the results obtained from the output generated
by the Plaxis software, the data was transformed into a line chart, with the dynamic time
element placed on the horizontal axis and the placed elements on the vertical axis such as Uy,
Ux, Ax, and Pexcess. Furthermore, it was observed that embankments constructed with sand
exhibit higher pore pressures in comparison to those composed of clay or gravel. This
phenomenon can be attributed to the compressibility of sand, which induces increased
volumetric strains and initiates pumping phenomena, ultimately leading to elevated pore
pressures. In contrast, materials such as gravel and clay demonstrated superior drainage
capabilities and decreased compressibility, facilitating the effective dissipation of excess pore
pressures.
