A closed-form solution is proposed to estimate the displacement of single piles in clay under one-way cyclic axial loads. This solution is an application of a creep displacement equation of piles under constant loads. The concept of equivalent creep load allows the solution to include the effects of both the characteristics of cyclic load and the mechanical properties of clay. The accumulated displacement under a cyclic load corresponds to the displacement due to the equiva-lent creep load. The results of model tests proved that the solution is useful in explaining the displacement of piles in clay under one-way cyclic axial loads.
