The pile foundation deformation in the high-speed railway bridge shows a small characteristic on the order of magnitude,and the bridge monitoring is often interfered by external conditions or random noise in the shape monitoring process,which makes the collected data and post-processing prediction data show a large fluctuation,and data analysis and subsequent deformation prediction will be affected.The multiple regression is introduced into the preprocessing of deformation data analysis of high-speed railway bridge.Considering the effect of temperature and load on the bridge,the multiple regre...
