工程放样中三角高程的精度分析

Precision Analysis of Triangle Height During the Engineering Setting

三角高程放样中,平面位置放样与高程放样都采用经纬仪,是一种快速的方法,但距离误差及高差误差与竖直角有很大的关系,本文对此进行了分析。同时分析了测距仪的放样精度。

In the triangle height setting,the setting of distance and height are all using theodolite.Therefore,it is a quick method.But distance error and height error are related with vertical angle.This paper analyzed the relationship and the precision of setting using Distance Measuring Equipment.
