Abstract
Seismic stability of embankment dams and their foundations has been a major concern in recent years because of notable incidents such as the behavior of the Lower San Fernando dam in the San Fernando Earthquake. Sophisticated and involved analytical methods have been developed to study the behavior of dams in earthquakes. Predicted seismic behavior agrees well with measured seismic behavior in the few case histories that exist of seismically induced distress in dams. However, for many dams, the level of information or effort required for a complete sophisticated seismic analysis is not warranted. For such cases it is possible to perform a simplified seismic analysis using a comparison of the results of rigorous seismic studies on dams with similar dimensions and material properties. One such comparative analysis procedure is presented with case histories showing how the techniques may be applied to actual studies.

Assessment of Seismic Stability of Earth Dams by Comparative Methods
Seismic stability of embankment dams and their foundations has been a major concern in recent years because of notable incidents such as the behavior of the Lower San Fernando dam in the San Fernando Earthquake. Sophisticated and involved analytical methods have been developed to study the behavior of dams in earthquakes. Predicted seismic behavior agrees well with measured seismic behavior in the few case histories that exist of seismically induced distress in dams. However, for many dams, the level of information or effort required for a complete sophisticated seismic analysis is not warranted. For such cases it is possible to perform a simplified seismic analysis using a comparison of the results of rigorous seismic studies on dams with similar dimensions and material properties. One such comparative analysis procedure is presented with case histories showing how the techniques may be applied to actual studies.
