ABSTRACT
Firstly, in this paper, based on the theory of the porous elastic medium and combined with
the effective stress principle of unsaturated soil, a set of governing equations is established
to describe consolidation of the unsaturated soil. Secondly, an analytical expression under
any dynamic loads is obtained with the help of Laplace integral transformation. Finally,
analysis of numerical examples under specific boundary conditions is made to discuss one-dimensional
consolidation characteristics under harmonic loads and the influence of factors
on the consolidation characteristics of unsaturated soil, such as excitation frequency and
initial saturation.
