Research on Simulation Process of Rock Broken by TBM Hob

Abstract:

The rock broken process was simulated by using finite element method based on the hob broken rock mechanism. The rock broken shape was analyzed by adjustment numbers of hobs and angles of hob. The destruction of rock was the presence of both compressive failure and shear failure. The main destruction of rock was compressive failure with single hob. The main destruction of rock was shear failure with multiple hobs. It could be found that the main destruction of hard and brittle rock was shear failure but shear failure of softer rock was relatively small through rock breaking process of three hob in different sequentially angles.
