摘要
本文推导了隧道贯通测量的精度估算公式,这个公式不仅考虑了测角量边精度对隧道测量的影响,而且还考虑了洞外控制点的精度对隧道测量的影响。最后给出了一个算例,得出了若干结论。
This paper derives the formula of the accuracy estimation of tunnel breaking-through survey, which considers the influence caused not only by the angular accuracy and the distance one on this kind of survey, but also that caused by the accuracy of control points out side the tunnel. Finally, an example is given and some conclusion are obtained.
