Evaluation of the dynamic behavior of pile groups considering the kinematic force of the slope using centrifuge model tests

Abstract

In this study, dynamic centrifugal model tests were performed by installing a pile group on the slope to examine the effect of the kinematic force of the slope on the pile. Based on the results of this experiment, a method for calculating the slope kinematic force applicable to the pile foundation was derived, and the pseudo-static analysis was performed. The results showed that the moment difference from the experiment occurred at the top of the pile by 14-49% in the analysis model without ground kinematic force, but decreased to 3-35% when the ground kinematic force was considered. In particular, in the lead pile, which is most affected by the ground kinematic force, the moment difference was less than 20% when the ground kinematic force was considered, indicating that the pile moment by depth was most appropriately simulated.
