Abstract The mixed ground is inevitable during the construction of tunnel by TBM, and it has a great influence. The linear cutting tests were conducted by the mechanical rock fragmentation platform of Beijing University of Technology. The rock sample of the mixed ground were composed of sandstone and mudstone. In order to verify the rock fragmentation mechanism and efficiency under different penetration, the rock breaking phenomenon, the cutting force, the specific energy and the rock debris composition were analyzed during the tests. The main conclusions could be summarized as follows: there were huge differences of cutting forces between the two kinds of rock, and the differences increased rapidly with the increase of penetration. The debris of the sandstone mainly consisted of coarse breccia and small gravel, while the debris of mudstone were primarily composed of breccia. Therefore, the rock fragmentation of the rock mixed ground could be simplified as a combination of rock breaking of different kinds of rock, which offered some guidance for design and construction of TBM.

Key words： the mixed ground linear cutting test rock fragmentation mechanism rock fragmentation efficiency
