摘　　要：The numerical analysis of static and dynamic performance of embankment dams using the finite difference approach is a complex procedure that takes into account material behavior,soil-dam foundation interaction,hydraulic conditions,and saturation effects.In this study,a numerical analysis using the finite difference method(FLAC 3D)is used to conduct a static and dynamic analysis of the Keddara earthen dam in the Boumerdes region of Algeria,with the goal of defining its behaviour in terms of settlement,deformation,and pore pressure variation during construction and operation.There are two steps to consider:dam construction and water filling.For the static analysis,two mathematical models are considered:the elastic model and the Mohr-Coulomb model.An actual earthquake record is used to conduct a coupled dynamic analysis,and the interaction between the fluid and solid phases is taken into account.Maximum displacement,acceleration,and pore pressure remain inconsequential for dam instability;horizontal and vertical displacements increase with distance from the dam body’s base to the top.
