摘要：
Based on the motion theory of three-phase poroelastic medium, the torsional vibration of a pile in unsaturated soil is investigated contemplating the impact of construction disturbance. The soil is segregated into a series of vertical annular zones, with the soil parameters of each zone varied to simulate its radial inhomogeneity. Subsequently, the governing equations for pile-soil interaction are formulated and solved, leading to the derivation of an analytical solution for torsional vibration in the frequency domain. Following a validation process, the proposed solution underwent parametric analysis to scrutinize the influence of soil saturation degree and construction disturbance on the torsional vibration characteristics of the pile.
