摘要：
This paper presents an analytical solution to investigate the vertical dynamic response of an elastic pile embedded in poroelastic soil overlying a rigid base. The pile top is subjected to vertical harmonic loading. The soil is modeled as a poroelastic soil layer underlying the base of the pile and a series of independent infinitesimally thin layers along the shaft of the pile. Using Biot’s poroelastodynamic theory and the method of Hankel integral transformation, the vertical dynamic response describing by the complex impedance is obtained. Following the verification of the derived solution against an existing solution, arithmetical examples are provided to parametrically analyze the influence of relevant parameters on the vertical dynamic impedance.
