摘要
地面沉降的模拟计算属于灰色问题,建立一个有效的灰色预测模型是十分重要的,在分析灰色线性回归组合模型模拟序列特点的基础上,建立了以原始数据直接建模的离散GM(1,1)模型(称为ODGM(1,1)模型),将某沉降实例数据建立ODGM(1,1)模型,并与灰色线性回归组合预测模型进行比较,结果证明离散GM(1,1)模型优于灰色线性回归组合预测模型。
Ground subsidence simulation is a grey system analysis. It is important to build an effective grey model. Based on the characteristic analysis of the analog sequence of grey linear regression combination model, a type of discrete GM （1, 1） model （ODGM （1, 1） model） is built with original data modeling discretely. Based on a case study of ground subsidence simulation, discrete GM （1, 1） model and grey-linear regression combination model are compared. Test results show that discrete GM （1, 1） is better than grey-linear regression combination model.
