Dynamic Response of Pile in Elasto-viscoplastic Soil under Vertical Vibration
This paper is concerned with the dynamic response of pile embedded in elaso-viscoplastic soil under vertical loading. The interaction between soil and pile is described by a five element model with a spring in series with a parallel dashpot and a spring combined with a parallel slider and spring, while the pile is treated as a column and described by elastic column vibration theory. In this model, total displacement of pile is assumed to be divided into three parts: elastic displacement, visco-elastic displacement and visco-plastic displacement. The final physical equations of pile embedded in elaso- viscoplastic soil under vertical vibration are established. Due to the nonlinearity of this problem, we use the finite differential method to solve the nonlinear partial differential equation. Numerical results indicate that the parameters of soil and the character of creep have considerable influences on the dynamic response of the pile.
