摘要
动态设计和信息化施工使得基坑结构变形预测意义重大,本文结合工程实践对GM(1,1)模型在基坑支护结构变形预测进行应用研究。工程应用结果显示灰色预测理论在深基坑结构变形预测方面具有较好的稳定性,GM(1,1)预测的深基坑地面水平位移、沉降与实际监测结果比较接近,GM(1,1)模型预测方法有效可行。灰色系统GM(1,1)基坑变形预测模型可作为基坑支护结构变形预测的参考工具。
Adjusting design and informational construction for deep pits made the pits＂ structure deformation forecast important. According to the project practice, application of GM （1,1） model in the pits＂ structure deformation forecast was studied in this paper. The results showed that the gray forecast theory has good stability in deep pits＂ structure deformation forecasting. There were a good agreement between the GM （1,1） forecasted struc- tures＂ displacement and surveyed displacement, subsidence, which suggest GM （1,t） deformation forecasting method was suitable. The GM （1,1） model could be served as a reference tool for the pits＂ structure detbrmation prediction.
