Abstract

 In this study, investigations were carried out on soft rock slopes with the aim of evaluating the stability of slopes, including post-earthquake residual displacement. First, the strength and deformation characteristics of the post-peak process were determined through triaxial tests in order to consider the effect of failure of soft rock masses in the modeling of the time history response analysis. Furthermore, for the evaluation of the amount of post-earthquake residual displacement of the soft rock slopes, the dynamic centrifugal model test and time history response analysis were carried out. As a result, the residual displacement of the analysis nearly matched that of the model test.
