Abstract
Precise guidance of the TBM (Tunnel Boring Machine) machine requires ensuring the accuracy of the drilling direction location at the level of +/- 1 cm for each kilometer of the tunnel with a length of almost 4 km. This means the need to determine and control not only the points of the implementation control network but above all the basic control network, the accuracy of which will be at the above-mentioned level. The article presents analyses that allow determining the technology of measuring this basic control network, in which an essential element was the connection of angular-linear measurements with gyro-azimuth measurements. This analysis also indicated the need to provide geodetic service using the highest accuracy instruments, which will enable the implementation of the design assumptions in the form of a transverse axis error at the end of the tunnel. The article also presents analyses of GNSS measurements confirming the determination of the accuracy of the reference points near the starting and ending chambers of the tunnel.
