N2  - Concerning the cutting mechanism of the cutter face in shield , some torque  components are not clear yet. In the theoretic model developed for automatic  operation of shield machine, these equations concerne<l were proposed based on  some assumptions, and were nol confirmed whether are correct or not.  A simplified model for cutting mechanism was used in the laboratory to study  the torque behavior exhibited in dry sand under the variance of each type of  parameter concerned, then formulated this torque behavior in advance, and  compared with the equation proposed in theoretic model.  From the experimental investigation, the results show that the equation for  torque of pushing resistance for sand is slightly different from that proposed in  theoretic model
