Abstract Research purposes：The subgrade deformation of high-speed railway must be controlled very strictly because of the high train speed on the railway and high technical standard required by the railway. Since many factors synthetically contribute to the deformation, so it is very important to synthetically and accurately analyze the factors involved and predict the time series law to the subgrade settlement.
Research conclusions：The multivariate nonlinear regression equation is established with the foundation of layer-summation method to illustrate the eternal relations among the time, settlement deformation, filling height, elastic modulus, and thickness of the compressed layer. Whats' more, the methods of multiple non-linear regression analysis of the time series data are given, and the applications show the methods can be wide used.
