Abstract
In this study, estimation method of seismic damage of railway embankment was proposed, complying with the current seismic design. The proposed method requires fundamental features of embankment, such as gradient or height, as well as magnitude, hypocentral distance and peak ground acceleration of the target earthquake. Given these parameters, the sliding deformation of embankment is estimated. Since the method requires only geometry of embankment, proposed method is also applicable for existing embankment, the design of which might not comply with the current design standard. The efficacy of the proposed method is confirmed by comparing the estimated damages with those observed in the 1995 Hyogo-ken Nanbu earthquake.
