Abstract:In this study, the rock breaking mechanism by disc cutter was investigated by using numerical method-RFPA 2D. Rock fracture process induced by a single indenter, double indenters and three indenters were simulated respectively. There were about four stages, powder body appeared, the formation of the powder nuclear body, the initiation and propagation of cracks, and broken blocks occurred respectively. And we carried out the disc cutter spacing optimization study when the multi-indenters function in rock; which would provide useful information for the design of Full Face Rock Tunnel Boring Machine and the arrangement of the indenters.
