 This paper examined the behavior of a single pipe pile constructed in two sand layers under two different conditions, dry and saturated. The results showed that the acceleration increased through the loose layer from the bottom to the top and then significantly settled within the dense layer. This suggests that the kinematic stress was greater in the loose layer than in the dense layer. Additionally, the bending moment was higher in the saturated sand soil than in the dry one, which may be attributed to liquefaction. Overall, this modeling can be used to estimate how a pile foundation will behave under kinematic loading driven by earthquakes.
