Observation About Axes of Arch Bridge Using Total Station and Analysis of its Measurement Results
In this paper,a simple arch axis observation method of arch bridge is proposed,which only needs to set two measurement points at the arch foot,and the total station can be set anywhere outside the arch foot.The coordinates of the arch axis of the arch bridge were ob-tained by measurement,and the scatter plot of the fitted front arch axis was drawn by SPSS software.The arch axis shape is determined based on the scatter plot.The arch axis equation of the hole is obtained by nonlinear regression analysis of the measured data,and the accurate arch axis is obtained.Experiments show that this method can reduce the workload in the field and improve the safety of operation.
