Abstract: An earthquake is a vibration of the earth produced by a rapid release of energy. An earthquake only occurs for a few brief moments; the aftershocks can continue for weeks; the damage can continue for years. The present work deals with an important and complex issue in geotechnical and earthquake engineering, which concerns the influence of both elasticity and pore water pressure on the seismic response of earthen dams to artificial earthquake records using the finite element program GEOSTUDIO QUAKE/ W.
The study includes observation during earthquake loading, the different methods of seismic analysis of earth dams. The study presents numerical analyses of the seismic behaviour of homogeneous and cored earthen dams. The analysis is first conducted for a simple case which concerns the elastic response of the earthen dam. This analysis provides some indications about the response of the dam, mainly the dynamic amplification and pore water generation. For the elastic analyses, a parametric study is conducted for the investigation of the influence of major parameters such as the mechanical properties of the earth material density and soil stiffness.
