Abstract
Associated with increasing global warming, changes in groundwater levels due to extreme precipitation and melting glaciers have a significant impact on slope stability. In this study, the 2D numerical simulation of the creep behavior observed through a centrifuge model test was performed using the finite element method, with a primary focus on the secondary region. Additionally, the constitutive parameters used in the model directly control the relationship between the factor of safety and the displacement rate, allowing for more flexible simulation of the measured time histories of sliding displacements under groundwater fluctuations. In conclusion, the analytical results were compared with the observed results, confirming the simulation of creep behavior. Moreover, it was verified that the usefulness of this model for the time-prediction of creep behavior, and it is considered valuable for preventing and mitigating landslide disasters.
