Abstract
The design of embankment, change to the performance design based on residual displacement from a design according to the safety factor is considered. Not only in the design of embankments but also in earth structure, the heterogeneity of the ground is usually disregarded. However, since the actual ground has heterogeneity, it needs to consider the influence that the heterogeneity has on the earthquake-proof stability of embankment. Therefore, it needs to consider the influence that it has on the earthquake-proof stability of embankment. This research performs reliability analysis in calculation of the safety factor and residual displacement of embankment.
