摘　　要：以宿迁苏豪银座项目为例,对基坑开挖过程引起的周围深层水平位移进行检测,并运用灰色理论和时间序列对实测资料建立模型,用此模型对后几期监测结果预测,计算结果表明灰色时序组合模型较单一的模型预测精度高,得出组合模型更适合于对该基坑变形监测数据进行建模的结论。Taking the Suhaoyinzuo project in Suqian city for example,the deep horizontal displacement around the foundation pit caused by foundation pit excavation is detected. The measured data is used to establish the model by using the grey theory and time series. The model is used to predict the next several monitoring results. The result shows that the grey time series combination model can provide better prediction accuracy than single system,and the combination model is more suitable for the modeling of deformation monitoring data of the foundation pit.
