Fragility curves for highway and railway embankments have been developed for a set of ground conditions and different embankment heights and widths. Ground consisted of liquefiable layer underlain by competent base layer and covered by clayey crust. Numerical time history analyses were used with PM4sand material model as implemented in FLAC code. A set of 30 recorded ground motions was used, which were scaled to different peak ground accelerations.
Criteria for three levels of damage states for derivation of fragility curves for traffic embankments were taken from the literature. The influence of the position and thickness of the liquefiable layer, its properties and the influence of embankment geometry on the fragility curves will be presented.
