| Abstract: | Efficiency of shield cutterhead changes along with working environment.In this paper,the excavating process is simplified as the interaction between cutters and soil.Finite element method(FEM) is used to simulate the excavating process of shield cutterhead.Based on the simulation,the influence of soil,construction control and cutterhead type on dynamic cutting load distribution and torque of cutterhead is analyzed. |

| Keywords: | cutterhead excavating load influence factor |
