Momentum Backpropagation for the Settlement Prediction of Subgrade Construction

The method of Momentum Backpropagation is employed on the prediction of railway subgrade construction. Combined with the concreted example of actual subgrade engineering, the BP neural network model for settlement prediction of roadbed in the railway is founded. The predicting results indicate that the model proposed can gain higher precision, which provides a new way for settlement prediction of the railway roadbed.
