Embankments, Earth Dams and Slopes
Abstract:
A methodology for seismic risk analysis of earth dams is described. The procedure utilizes seismological and geotechnical inputs together with the associated uncertainties and provides estimates of seismic risk of damage and failure of earth dams. An example case study of an earth dam is described and the benefits of the procedure in a risk-based decision analtsis of seismic rehabilation of the dam is illustrated.
The research described here was funded by a grant from the National Science Foundation. The writers greatfully acknowledge this support.
