Abstract
Theory about the interaction of TBM disc cutters and rock mass is critical for the design of the TBM machine. The numerical model of the interaction between cutters and rock, has important theoretical and practical meaning for developing a complete forecasting model of TBM performance. In this paper, one TBM disc cutter model is established based on finite element meshes. Then a model of full-face TBM cutterhead with several discs is presented for analyzing the strain distribution from start to rock failure.Meanwhile a Generalized Finite Element method (GFEM) simulation of a single crack propagation is shown in this paper. This numerical model simulates crack propagation under symmetrical loading and unsymmetrical load, respectively. The propagation path resulted in numerical simulation accords well to the laboratory tests
