According to the single layer viscoelastic foundation model, the paper starts from the Fourier series of the cyclic loading, concludes the analytical solutions to the viscoelastic one-dimensional consolidation of impeded boundaries under cyclic loading by the consolidation formula, achieves the hole pressure change law for any boundary foundation under the loading along with the time changes, so as to provide the direction for the engineering construction in soft clay areas.
