加权组合模型在路基稳定性评判中的应用
Application of combined weighting model to judgment of subgrade stability
摘要
Abstract
On the basis of double-curve model and grey model, a new combined weighting model is built on the condition of the minimal absolute values of errors. The formula derivation and actual measurement results show that the predictive error of the combined weighting model is reduced in comparison with those of the two former methods. Meanwhile, on the basis of the actually surveyed data and predicted values derived from the combined weighting model, the ratio of weak intercalated layers compression amount to total settlement is regarded as evaluation factor, and by the change curve of evaluation factor, tendency of subgrade stability is evaluated. Finally, the simplicity and feasibility of this method is validated through actual examples.关键词
