摘要
本文从全站仪两种不同的施测三角高程测量方法的原理出发,得出两种不同的施测三角高程测量的计算公式,并对各公式进行误差来源分析,应用误差传播定律得出各自的误差方程式,并进行精度分析比较,最后得出在一定范围内合理利用全站仪三角高程测量,可达三、四等水准测量的要求。
From the two different approaches of Triangle Elevation Surveying by using total station, two calculation formulas were deducted. Then after error analysis, the error transmission principle was applied to figure out the error formulas respectively and then a contrastive analysis was made for each elevation survey accuracy on the impact of various factors. The analysis results show that if Triangle Elevation Surveying by using total station was applied within certain reasonable ranges, the observation result could reach the water leveling survey measurements of grade three or grade four specifications.
