摘要
推导出了最佳贯通点和横向贯通误差的预计公式,并在此基础上给出了任意点的贯通误差预计公式及贯通误差曲线。通过贯通误差曲线,可方便、直观地得到横向贯通误差。
This paper starts with the analyzing of the lateral breakthrough errors caused by traverse survey, deduces the formulas of optimum breakthrough point and the predicting formulas of lateral breakthrough errors. On the basis of those formulas, the predicting formulas of the random breakthrough point＇ s errors and the breakthrough error curve are presented at the same time. Thus the lateral breakthrough errors can be expediently gotten through the breakthrough error curve.
