Prediction method of subgrade deep horizontal displacement
摘要
Abstract
The study on subgrade deep are studied horizontal displacement is not sufficient.Several displacement prediction methods,and matching prediction models is built to predict horizontal displacement.Referring to the posteriori error ratio and small error probability,we get the following results.GM(1,1) model is suitable for predicting the subgrade horizontal displacement,and the trend of GM(1,1) model is consistent with actual values.Its accuracy is higher than the logarithmic curve fitting and the stability is better than the exponential smoothing model.关键词
