| 摘要 |
This tunnel boring machine (1) comprises a data processing device (23) that acquires error data (Er) on the basis of a current measurement value (Vp) of a strain sensor (22) acquired at a current angle (θ) of a cutter head (11) and of a past corresponding measurement value (Vo) acquired in an angle of rotation corresponding to the current angle and that corrects the current measurement data using the error data. |
