Abstract: A nonlinear concentrated spring model is presented in this paper, and the model is applied to the analysis of elastic plate-nonlinear subgrade interaction . The computation result shows that the subgrade reaction , the deflection and bending moment are improved greatly if the non-linear property of subgrade is considered.

Key words: nonlinear subgrade ;elastic plate , interaction
