The pseudostatic analysis performed at the first step confirmed that the study slopes could not fail without strong earthquakes. However, further dynamic analysis performed by use of the Newmark method allowed...

Therefore, earthquakes and rock bursts are mainly...

ABSTRACT: Since the 1999 Chi-chi earthquake and the 1999 Kocaeli earthquake damaged many important structures due to surface rupture, as well as a strong motion by the fault rupture, displacement and inclination in ground surface become the significant issues. In this study, we conducted fault...
