To improve the earthquake resistance of soil embankments, it is crucial to clarify the crack initiation and propagation processes. Peridynamics is a powerful method for such analyses. In the present study, a crack propagation analysis of a compacted clay embankment is conducted using OSB-PD with seismic waves of several maximum accelerations and frequencies. The results show typical failure patterns of embankments during the earthquakes, such as cracks in the slope and shear failure (i.e., a sliding surface).
