| 摘 要： | 针对传统GM（1,1）模型的不足,分别从提高原始序列的光滑度、优化背景值、优化时间响应函数三个方面对其进行了改进,对模型进行后验差检验进行模型精度检验,并建立了一种新的GM（1,1）模型,将改进了的模型应用于大坝沉降预测中,结果显示,新的GM（1,1）模型拟合预测精度明显高于传统模型.

| Abstract: | In view of the deficiency of traditional GM(1,1) model,this paper sets up a new GM(1,1) model from three respects of improving the smooth degree of the original series,optimizing background values and optimizing the time response sequence.The new model is used in the prediction of dam settlement,the result shows that the fitting and prediction precision of the new GM(1,1) model is higher than the traditional GM(1,1) model. |
