摘要：

This article proposes a new analytical model for the low-strain integrity detection of a pipe pile embedded in a viscoelastic soil layer with radial inhomogeneity by extending Novak's plane-strain model and transfer method of complex stiffness to consider viscous-type damping. The analytical solutions for the complex impedance, the velocity admittance and the reflected wave signal of velocity at the pile head are also derived. Extensive parametric analyses are further conducted to investigate the effects of the disturbance degree and the disturbance range of surrounding soil due to construction operation on the velocity admittance and the reflected wave signal of velocity at the pile head. It is demonstrated that the proposed model and the obtained solutions can provide extensive scope of application, compared with the relevant existing solutions.
