Vertical Dynamic Response of a Pile Embedded in Viscoelastic Soil Considering the Effects of Lateral Rigid Boundary
To obtain the dynamic response of vertically loaded pile close to rigid boundary, a computational model of a pile embedded in viscoelastic soil is established. Based on plane strain assumption of the soil, axisymmetric governing equation in cylindrical coordinates system is established. To obtain zero displacement for the rigid boundary condition, mirror method is adopted to solve the governing equations of the soil. The dynamic response of pile is then obtained based on the perfect contact condition on pile-soil interface. The present solution is validated through comparisons with Novak’s solution. The effects of pile length and distance from the rigid boundary are analyzed. The results are potentially useful to understand the vibration characteristics of piles constructed in irregular topography and geology conditions.
