Undrained behavior of composite clays in its natural or compacted state e.g., core material of embankment dams has a great importance for the geotechnical engineers. On the other hand, experience has shown that significant pore pressure could build-up during cyclic loading in composite clays. In this paper, the results of dynamic analyses performed on Karkheh embankment dam in Iran, incorporating different core materials, are presented. Appropriate models for the core materials are utilized, based on the laboratory test results. The Newmark method is used to evaluate the permanent displacement. It is shown that seismic pore pressure build-up in composite clays can significantly increase the Newmark permanent displacement.
