全站仪导线测量若干问题的探讨

文章就全站仪导线测量的基本概念、原理、操作步骤以及其近似平差方法等进行探讨,指出全站仪导线测量的实质为全站仪"三维坐标测量"的连续进行,其形式为三维支导线,缺乏检核,因此在实际工作中,全站仪导线测量一次发展支点不宜过多、路线不能过长;否则,应从一已知点出发测至另一已知点以资校核,此时其闭合差应与导线边长成正比反符号进行分配。

Discussion on some problems of total station traverse survey

In this paper,some issues of total station traverse survey such as basic concept,principle,operation step,approximate adjustment method are discussed,and useful conclusions are obtained.The substance of to-tal station traverse survey is a three-dimensional coordinates measure in succession,and its form is a three-di-mensional unclosed traverse.So it is suggested that the total station traverse survey should be conducted without too many points and too long route for each time.Otherwise,it should be checked from one known point to another with proportional anti-symbol allocation between closing error and the length of side.
