| Abstract: | Based on the Beijing-Shanghai high-speed railway bridge pier subsidence monitor data,we find a suitable high-speed railway bridge pier fitting model with the current several common methods for deformation analysis and forecasting.Eeperimental results show that the GM（1,1） model can better improve the accuracy of settlement trends. |
