| Abstract: | Displacement time series are calculated precisely at single epochs based on real\|time and dynamic monitoring for large buildings by GNSS. It is found that the displacement has some prominent law, and the principal component of the displacement series is extracted by the spectral analysis method. The displacement forecasting model is established by high order harmonic function. Taking Tongji mansion for example, the forecasting result is consistent with actual observation series. The Root Mean Square (RMS) is better than 3 mm in horizontal direction and 7 mm in the vertical direction. These results are significant for automatic deformation monitoring and issuing early warnings in the event of abnormal deformations of large buildings. |
