利用全站仪对边测量功能测设路线横断面

Method of Using Total Station′s Edge Survey Function to Locate Cross-section of Route

该文推出了在线路坐标系下任意中桩点的切线方位角计算通式,求出了该中桩处横断面上点的坐标。基于全站仪具有放样测量、坐标测量和对边测量功能的特点,提出了一种简单灵活的横断面测量方法,是实现横断面的快速准确测量的有效途径。

The paper gives general formula of calculating tangent azimuth of random central stake points at highway central line coordinates. The coordinate for random point in cross-section is resolved. A simple and flexible method of cross-section location survey is presented based on total station＇s location survey and coordinate survey and edge survey functions. It is a way to survey railway cross-section efficiently and accurately.
