In a sewer tunnel, cutter bits were exchanged on the way because the excavating distance was long such as 4, 435m. The geology of constructing site composes of hardened silt and loosened sand. It is desirable for us to exchange bits in a good geological condition. So, we had developed a technology to distinguish the face geology by the difference of cutting vibration level between silt and sand. At first we carried out experiments to make clear the difference of cutting vibration and applied the technology in the field. We were able to clarify the geology where the cutter bits were exchanged.
