摘要
提出了一种简易可行的拱轴线测定方法,该方法利用全站仪将测站设在拱脚外任意位置,只在两拱脚处设测点进而对拱桥拱轴线进行测量。通过现场测量取得拱桥拱轴线坐标数据,利用SPSS软件绘制出拟合前拱轴线散点图,依据散点图在确定拱轴线形状后,通过对测量数据进行非线性回归分析,进而求得该孔的拱轴线方程,获得精准的拱轴线。实验表明,该方法可减少外业工作量,提高了作业安全性。
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 obtained 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.
