摘要
本文针对全站仪导线三种常用的简易平差方法进行了分析,结果表明,简易平差的精度与导线的形状以及闭合边的方位有直接关系。曲折导线特别是曲折度比较大的导线,采用旋转法时应持谨慎态度。全站仪导线因只与一条固定边进行了联测,精度降低比较明显,通过对等边直伸导线进行分析发现,靠近末边的点精度降低近一倍。
Three simple adjustment methods for total station traverse are discussed in this paper. Results of analysis show that the precision of simple adjustment is directly related to the shape of traverse and the direction of closed edge .When the shape of traverse is tortuous, especially its sinuosity being large, we use the rotation method should be cautious. Because total station traverse is only with a fixed edge in surveying, its accuracy is obviously reduced. The author analyses the accuracy of the equilateral and straight traverse, and results show that the precision of the point near the edge at the end of traverse lower nearly doubled.
