COSEISMIC FAILURE ANALYSIS OF EMBANKMENTS USING 3D EARTHQUAKE RESPONSE AND CRACK PROPAGATION ANALYSIS METHOD [Translated Paper]

抄録

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. In a previous study, we conducted a crack propagation analysis using Peridynamics (PD) to examine various embankment damage types. The results showed that the type of damage varies with the maximum acceleration and frequency. However, the analysis was limited to two dimensions. Therefore, in this study, a three-dimensional seismic response PD was developed and compared with the two-dimensional PD to demonstrate the validity of the code. We also investigated the influence of the maximum acceleration and frequency on the failure modes.
