摘    要:介绍了灰色系统理论。针对传统GM(1,1)模型在建模时只从静态角度考虑未来时刻的状态这一缺陷,本文引入了可以实时加入系统最新信息的动态GM(1,1)预测模型。利用传统GM(1,1)模型与动态GM(1,1)模型对某桥梁监测点进行沉降变形分析与预测。通过对比分析实例计算结果表明,动态GM(1,1)模型可以有效地修正预测模型,在一定程度上提高了模型的预测精度,其预测效果优于传统GM(1,1)模型。

关 键 词:沉降变形  动态GM(1    1)  变形预测

Abstract:This paper introduces grey system theory. Aiming at the deficiency of traditional GM ( 1,1 ) model consid-ering future state only in a static view, this paper introduces the dynamic GM ( 1,1 ) prediction model that can add latest information into system in real time. Using traditional GM (1,1) model and dynamic GM (1,1) model to analyze and predict a bridge monitoring point settlement deformation Through comparing and analyzing the calculation results of pro- ject example shows that the dynamic GM( 1,1 ) can effectively revise prediction model and improve the prediction preci- sion of the model in a certain extent, its prediction effect is superior to the traditional GM ( 1,1 ) model.
Keywords:settlement deformation  dynamic GM(1  1)  deformation prediction
