| 摘 要： | 人们以往对全站仪中间法三角高程测量代替三、四等水准测量讨论较多,对代替二等水准测量的问题则较少涉及。本文通过对中间法三角高程测量公式的精度估算及分析,以及大量实测高差数据的统计,验证了用中间法代替三、四等水准测量的高可靠性和代替二等水准测量的基本条件。

| Abstract: | There are more discussions on the middle method o f total station for replacement of the third and the fourth grade leveling.But there are few discussions on the replacement of second grade leveling.This pape r estimated and analyzed the precision of the formula of middle method trigonome tric leveling.It also gave the statistics of massive observed height difference data.Then it proved the high reliability of the middle method of total station for replacement of the third and the fourth grade leveling and basic condition of the replacement of second grade leveling. |
