The well-known empirical e-lgσ' relation is introduced into the study on one-dimensional nonlinear consolidation of one-layered soil under cyclic loadings. The corresponding consolidation equation is established with the assumptions that the decrease in permeability of soil is proportional to the decrease in compressibility during the consolidation process and that the distribution of initial effective pressure does not vary with depth.
