Study on Mechanism of Rock Fragmentation of TBM Disc Cutter
As the interaction mechanism between disc-cutter and wall rock is the key to the TBM performance of breaking-rock, many exports who come from different countries have so far made a great deal of studies, tests, analyses and modeling works and many models of mechanism of rock-fragmentation were achieved. Some new corrections are made constantly according to the experiences accumulated from engineering practice. This paper summarizes the works of the scholars and some analyses and comparisons are made. Based on the CSM and NTNU, a new model is presented to takes into account some ingredients, which would influence the efficiency for TBM to break wall rock. To enhance the level of design, manufacture and operation of TBM, the databases for rock attributes, main parameters of TBM and excavating parameters should be found.
