| Abstract: | The influence of errors on the through-survey is discussed with construction of Xi＇ an metro line 2 tunnel. A feasible scheme using Gyro Total Station measurement is proposed. Data processing theory and method are also introduced with a successful tunnel transfixion case. The results show that through error can be eliminated effectively by including gyrotheodolite azimuth and the traverse accuracy and reliability can be improved. |
