| 摘 要： | 灰色系统理论在岩土工程领域已经有着广泛的应用,其中以灰色理论中的GM(1,1)模型为最。本文基于GM(1,1)的建模机理,从原始序列、初始值、背景值等方面对其进行优化,并将改进后的模型应用于某基坑工程的变形预测。结果表明,改进后模型的预测结果与实测结果拟合得效果很好,较之原GM(1,1)模型预测精度要高。

| Abstract: | Grey theory,especially GM (1,1) model,has been widely used in the filed of geotechnical engineering.Based on the mechanism of GM (1,1) model,the original data sequence,initial vale and background value of the model have been optimized.Accordingly,an improved grey prediction model is proposed and applied in an actual example of foundation pit deformation prediction.The improved grey model has higher precision than the common GM (1,1) model. |
