基于灰色理论的黄土高填方地基沉降变形预测研究

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)模型对于高填方地基沉降不仅在短期精度高,随着施工的进行对于中长期精度也可以保证,这既可缩短工期、降低工程成本,又能提高工作效率。

Study on Settlement Deformation Prediction of Loess High Fill Foundation Based on Grey Theory

Taking a loess high fill project as study object,this paper established GM (1,1) model predicting the settlement deformation thereof and,with Matlab program and actual monitoring data,made the short-,medium-,and long-term predictions.The results show that GM (1,1) model,for high fill foundation settlement,has high accuracy in short-term prediction and,as the construction is going on,the accuracy in medium-and long-term prediction may be guaranteed as well,which may shorten the construction period,reduce the project cost and improve the work efficiency.
