| Abstract: | The paper analyzed the cutting mechanism of TBM(Fullface Tunnel Boring Machine) in Qinling tunnel, which was applied to railway tunnel construction in our country firstly. Considering the fact of rock breaking shape and cutter wearing, established the thrust force model and then expanded it to the cutter head. The relationship between the depth of penetration, normal force and the strength of rock had been numerical analyzed, thus we selected the reasonable parameters of TBM possibly. |
