摘要
介绍了全站仪三角高程测量的原理,推导了其高差观测精度公式。利用某一区域部分点间的三角高程对向观测反求此地的大气折光系数,然后对全站仪单向观测的高差进行改正,并将此方法应用到中国散裂中子源(CSNS)园区地面标高测量中。
This paper analyzes the principle of triangulated height surveying,and deduces a formuls to estimate height accuracy.Using reciprocal observations between several points in a region by trigonometric leveling,the methodology produces the atmospheric refraction coefficient,then the effects of atmospheric refraction in the other observations are corrected.This method is applied to the measurements of ground elevation in China Spallation Neutron Source（CSNS）.
