Based on the Biot’s dynamic consolidation equation and Novak’s plane strain theory, a coupled mechanical model of radially heterogeneous saturated soil and wedge-shaped pile was established under the horizontal vibration, by considering the construction disturbance effect of the surrounding saturated soil. Then, the analytical solution for the horizontal impedance of the pile head was obtained by using the potential function, Laplace transformation and variable separation methods, and the accuracy of the solution was verified by degenerating with the existing literature solutions. On this basis, the effects of the pile’s parameters and construction disturbance effect on the horizontal vibration characteristics of wedge-shaped pile are further discussed by conducting an extensive parametric analysis. The results show that: The horizontal impedance of the pile head tends to be stable when the number of pile-soil system layers reaches 100. With the increase of softening degree and range of surrounding saturated soil, the horizontal impedance of the pile head decreases, while both the horizontal displacement and bending moment of pile shaft increase. The reasonableness and reliability of the analytical model and solution proposed in this paper are verified by comparative analysis in many aspects.
