摘要
对我国铁路隧道首次使用的全断面掘进机在秦岭隧道施工中的破岩形式和机理进行了分析，基于其破岩形式和刀具磨损情况，界定了单把刀的推力模型．进而将其扩展到整个刀盘，对不同切深和岩石强度下的推进力进行了数值计算，为掘进机主机工作参数的选取奠定了基础．
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.
