摘要在特长隧道中，将已有的控制网数据引进隧道后，利用两个以上隧道大地坐标建立独立施工坐标系，在独立施工坐标系的基础上进行测量作业，简化了测量作业步骤，数据简单、直观、计算简化，缩短了测量内外业工作时间，减少内业时间及人为因素产生的错误。利用建立的独立施工坐标系和计算器程序，应用于隧道施工放样及断面检测等方面。

Abstract： Independent construction surveying coordinate system can be established in super-long tunnels by making use of more than two geodetic coordinate systems after introducing the existing data of control net into the tunnel, which can simplify the working procedures of measurement, shorten the time of both interior and outside measuring work and interior work time, and reduce the mistakes due to personal factors. This independent construction surveying coordinate system together with calculator programs can be applied to tunnel construction lofting and cross-section inspection.

Keywords： Independent construction coordinate system, Straight line tunnel, Curved tunnel, Program
