摘　　要：在分析传统模型建模的不足的基础上,介绍了一种实时引人新信息的等维灰数和等维新息递补动态预测方法。根据某广场变形监测数据,首先建立GM(1,1)模型,再用灰色理论的方法,分别建立等维灰数和等维新息递补模型,并根据实际观测数据,讨论最佳建模维数,最后将3个模型预测效果进行对比。结果表明,与原始的灰色GM(1,1)模型相比,等维动态方法建立了一种数据之间的动态关系,特别是实测值的加入,能够有效提高模型精度,获得良好的预测效果,是一种既方便又可靠的变形分析方法。After the analysis the fall shortage of the traditional model of gray system theory,this paper introduces dynamic prediction method equal dimension gray data and equal dimension new information which introduce new information by real-time.Based on deformation data of some square,first established GM（1,1） model and then established respectively recruiting model of equal dimension gray data and equal dimension new information,and according to the actual observation data,discusses best model dimension,finally,the prediction effect of three models was compared.The results showed that equal dimension dynamic method builds the dynamic relationship between the data compared with the original grey model GM（1,1）,especially the addition of the measured values,can improve effectively the accuracy of model,obtain good precision,is convenient and reliable method of deformation analysis.
