铁路既有曲线整正测量方法

Survey and Rectification Methods for Operated Railway Curvature Line

给出了全站仪任意点设站测量既有曲线上点的坐标的方法 ,对曲线整正中的半径选择 ,缓和曲线长度选配 ,拨距计算方法进行了探讨 。

This paper deals with the method of how to use the electronic-total-station instrument,placed at any point,to determine the coordinates of points of points on operated railway curvature line.It also studied the problems related to the rectification of curvature line,such as the selections of the radius,the length of spiral easement curve as well as the curve as well as the curve vector,which can be directly used in rectification work of operated curvature line.
