Summary: This paper presents an analytical solution for one-dimensional consolidation of soft soil under some common types of cyclic loading such as trapezoidal cyclic loading, based on the assumptions proposed by E. H. Davis and G. P. Raymond [Geotechnique 15, No. 2, 161–173 (1965)] that the decrease in permeability is proportional to the decrease in compressibility during the consolidation process of the soil, and that the distribution of initial effective stress is constant with depth. Our solution is verified by analytical solutions existing in special cases. Using the solution obtained, some diagrams are prepared and the consolidation behavior is investigated.
