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.
