Abstract
The settlement prediction is an important problem to railway subgrade design and construction in the collapsible loess region. Prediction of subgrade settlement is more methods through measured data in practical engineering. Based on the long-term monitoring data of settlement of loess subgrade at Lanzhou-Wuwei second-railway line, a new prediction model was put up and contrasted with other models such as Hyperbolic model, Logarithm model, exponential model and Poisson’s model. The results showed that the new model could be better predict settlement laws of loess subgrade, and agreed well with hyperbolic model forecast results, and proved the correctness of the model.
