Coseismic Failure Analysis of Embankments Using 3D Earthquake Response and Crack Propagation Analysis Method

Abstract

The types of embankment damage during earthquakes are crest or slope tension cracking and circular sliding. However, it remains unclear which damage occurs during which earthquake. We conducted a crack propagation analysis using peridynamics (PD) to study type of damage of embankments. The results showed that the type of damage varies with maximum acceleration and frequency. However, the analysis was limited to 2D. Therefore, a 3D seismic response PD is developed and compared with the 2D PD to demonstrate the validity of the code. We also investigate the influence of maximum acceleration and frequency on the damage.
