| Abstract: | In this paper a survey method has been introduced,by which the central 3D coordinate of shield tunnel's entrance/exit ring can be obtained,Furthermore,when excess observations are available,the procedures and methods of processing the observation data and solving the 3D coordinates of shield tunnel's entrance/exit ring have been addressed.This method can be used for reference in the analogous case. |
