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 Suqian Ginza Project in Suqian as an example, the deep horizontal displacement caused by the excavation of foundation pit was detected. The gray theory and time series were used to establish the model for the measured data. The model was used to predict the monitoring results in the later period. The calculation results The results show that the gray time series model is more accurate than the single model, and the conclusion is drawn that the composite model is more suitable for modeling the deformation monitoring data of the foundation pit.
