摘要
本文详细介绍了时空自回归模型的基本原理及其具体建立步骤。同时基于大型桥梁实际GNSS监测数据建立预测模型,对该方法进行检验。实际预测精度计算结果以及与其他方法对比表明:该方法预测精度较高,考虑了建筑物整体变形的影响,具有较高的实用价值。
This paper introduces the basic principle and the concrete steps of the spacetime auto-regressive model.At the same time,based on the actual GNSS monitoring data of large bridge,the forecasting model is established,and the method is tested.The results of the actual prediction and comparison with other methods show that the method has higher prediction accuracy,and the effect of the whole deformation of buildings is considered,which has high practical value.
