本文介绍了在微机上利用野外测量成果计算测线交点桩号和井桩号的原理和方法,并编制了相应微机程序。本程序灵活,方便,实用性强,具有下列特点:(1)计算结果既能以表格形式输出,又能以测线底图形式输出;(2)数据库能方便地增删和修改,并能简捷地输出新成果。应用结果表明,这种方法消除了人为误差和随比例尺引入的误差,避免了繁琐的人工劳动,极大地提高了精度和效率。

This paper presents the philosophy and methodology in defining the intersection points of survey lines and well locations in a computer aid way based on geodesic measurements. A computer code has been devcloped which is both practical and flexible and has features as follows : (1) its calculating results can be given either in tabular form or with a map of survey lines, (2) its database can be easily appended, deleted or modified and the subsequent results are yielded rapidly. Practice showed that this method is capable of reducing errors whether they are artificial or caused by scaling. As a consequence of applying the method, heavy manual operations are avoided and efficiency and accuracy are improved.
