摘要
在原始传统GM(1,1)和新陈代谢动态灰色模型的基础上,建立了傅里叶变换修正动态残差的新陈代谢灰色模型。结合工程实例沉降数据,用原始传统灰色模型、新陈代谢灰色模型、动态残差修正的新陈代谢GM(1,1)三种模型进行短期和中长期沉降预测分析比较,结果动态残差修正的新陈代谢GM(1,1)模型比动态灰色模型、原始传统灰色模型的预测精度均有所提高,并有一定的收敛性和较好的预测效果,为今后的沉降预测评估提供了一定的参考。
On the basis of traditional GM（ 1,1） and the metabolic dynamic gray model,Fourier transform is applied for modification of dynamic residuals in the gray model. Based on the sedimentation data of engineering examples,the short-term and medium-long-term settlement prediction are compared with that of the traditional GM（ 1,1） model and the traditional gray model. The results show that the prediction accuracy of new method is improved,and there is some convergence and good prediction effect.It provides some references for future application on settlement prediction.
