High-speed railway subgrade settlement forecasting is an important part to ensure ride comfort and stability of the high-speed railway line. Based on the measured settlement data of Lan-Xin Railway DK649+500D-K650+000 section, three kinds of single forecast methods, including Hyperbolic method, Three-point method and Asaoka method are adopted for the high-speed railway subgrade settlement forecasting. The least squares support vector machine in adopted for its unique advantages in solving small sample data and nonlinear data. Combination forecast model is established by setting different weights of the single forecast methods. Simulation results show that the systematic errors in the Combination forecast model are less than that in the single forecast methods. Compared with the single forecast methods, the Combination forecast model has higher forecasting accuracy and better applicability.
