It is important in engineering practice that reliability analysis of embankment must be done considering uncertainties as well as randomness in load and resistance. The present study deals with reliability of embankment when a major earthquake occurs. First, the authors present a seismic reliability analysis of embankment in consideration of randomness and uncertainties of load and resistance using point estimate method. The objective of this paper is to develop the reliability analysis in order to evaluate the failure of embankment due to pore water pressure build-up. Secondly, the influence of randomness and uncertainties in the seismic load and resistance of embankment itself on the damage assessment is also discussed. Finally, the method is applied to the embankment damaged in the past earthquake.
