Abstract Research on the subgrade accumulated deformation has a significant meaning to the dynamic stability analysis in traffic engineering. By analyzing the results of the cyclic dynamic triaxial tests，whether in the drained or undrained conditions，for both saturated normally consolidated and overconsolidated clay，the pore water pressure and accumulated plastic strain are considered to have a certain relationship. Through improving the Terzaghi-Nicolson consolidation formula and studying the relationship between the pore water pressure and the accumulated plastic strain，a new accumulated plastic strain nonlinear predicting model for the saturated clay is proposed. The model can predict not only the variety of the pore water pressure in the clay，but also can predict the development of the soil accumulated plastic strain. The model validation shows that the developed model can well reflect the developments and changes of the saturated clay pore water pressure and accumulated plastic strain.

Key words： soil mechanics cyclic load saturated clay pore water pressure accumulated plastic strain nonlinear model
