在隧道掘进过程中，刀盘扭矩的计算关系到工程的进度及质量，由于复合地层地质情况多变，其扭矩计算比软土地层更为复杂，软土地质情况下的公式仅适用于计算叶片的搅拌扭矩，然而复合地层中复杂的软硬地质变化会同时影响刀盘与地层的摩擦阻力矩、地层的抗力扭矩和刀盘正面与地层的摩擦力矩。为了更进一步完善复合地况下的盾构刀盘扭矩计算方法，针对复合地质情况进行了一定的研究分析，并以此为依据制定了复合地层下的扭矩计算方法。

Compared with the soft formation ,the torque calculation of cutter in mix ground is more complex .In the mix ground ,the formula of soft formation can be only applied to the calculation of mixing torque ,in the calculation of the frictional resistance torque between the cutter and soil and the resistance torque of ground ,we should take the change of geological condition into consideration . Based on the study of different geological condition , this article presents the method to calculate the cutter head torque in mix ground .
