| 摘 要： | 以银川大世界商务广场的基坑为例,介绍了大型基坑工程水平位移监测的实施方案,给出了水平位移监测方法的精度,并对监测成果进行了分析。在此基础上,分别用多项式拟合和时间序列分析模型两种方法进行建模,对基坑水平位移进行预测,结果表明,该基坑水平位移较小,在规范规定的要求之内,说明基坑是稳定的;时间序列分析模型的预测精度要高于多项式拟合模型的精度。

| Abstract: | Based on the Yinchuan world commerce square foundation pit, the implementing scheme of the horizontal displacement monitoring is given in this paper. The accuracy of the monitoring method is obtained by calculation. By using the historical data, polynomial-fitting model and time series analysis model are used to predict the future data of horizontal displacement. The results show that horizontal displacement is small to meet the specification, which means that the foundation pit is stable. The instance indicates that accuracy of the time series analysis model is better than the polynomial-fitting model. |
