Performance prediction of TBM disc cutting on granitic rock by the linear cutting test

This paper aims to estimate the TBM disc cutter performance on Hwandeung Granite, one of the representative rock types in Korea by the Linear Cutting Machine. In the Linear Cutting test, the digital photogrammetric technique was newly adopted to measure three-dimensional cutting volumes and to apply them to the derivation of design parameters of TBM cutterhead. In this study, a series of linear cutting tests by a TBM disc cutter with the...
