摘　　要：以某黄土高填方工程为研究对象,建立黄土高填方沉降变形的GM(1,1)预测模型。运用MATLAB编程程序并结合工程实际监测的数据,分别对黄土高填方沉降变形进行了短期、中期及长期预测。结果表明,GM(1,1)模型用于预测高填方地基沉降,不仅短期的预测精度高,中长期的预测精度也可以保证,可以大大缩短高填方工程施工工期,降低工程成本。Loess high fill engineering as the research object, a GM（1,1） model was established to predict its settlement. While settlement was predicted, Matlab was chosen to program. Based on the monitor data of the practical engineering, prediction was completed on the short term and long term. The results show that the above model is of high accuracy for both short-term and long-term prediction. It can shorten the construction period and reduce the cost for high fill engineering.
