Theoretical Model for Estimation of Cutter Head Torque in Shield Tunneling
-
摘要: 为给盾构选型、设计提供理论参考,通过对刀盘扭矩构成因素的全面分析,建立了刀盘扭矩估算的理论模型,导出了各扭矩分量的计算公式,并通过实例验证了模型的正确性.研究结果表明,刀盘背面的摩阻力扭矩和刀盘开口内土体的剪切阻力扭矩是不能忽略的因素.Abstract: In order to provide a theoretical reference for the design and type selection of shield machines,a theoretical model was proposed based on the systematic analysis of cutter head torque in shield tunneling.Formulae of calculating torque components in this model were deduced,and the validity of these formulae was proven by using an instance to show the correctness of the proposed model.The research results show that in the model,the effects of the shear resistant torque on the back of shield cutter head and the shear resistant torque induced by earth in the hatch of shield cutter head can not be neglected.
