摘要
GM(1,1)模型与灰色Verhulst模型是广泛应用于变形分析预测的两种经典预测模型。本文利用这两种模型分别对地铁竖井沉降数据进行分析预测。通过对预测数据的比较分析,得出了灰色Verhulst模型的预测精度更高,更适合于地铁竖井沉降的预测分析。
GM ( 1,1 ) model and gray Verhulst model are two classical models which are widely used in deformation analysis and forecast. This paper analysis and forecast subway shaft sedimentation data by using two kinds of model . Through the comparison of forecast data,we verified the prediction precision of the grey Verhuls is higher,it is more suitable for the analysis and forecast of the subway shaft sedimentation.
