对盾构机外载荷、推力、刀盘扭矩及功率等关键技术参数进行研究,分别运用理论公式和经验方法进行分析讨论。并结合某隧道施工中选用的土压平衡盾构机,对关键参数进行了校核计算。
The key technical parameters such as the external load, thrust force, cutter torque and power of the shield machine are studied, and the theoretical formulas and empirical methods are respectively used for analysis and discussion. Combined with the earth pressure balance shield machine used in the tunnel construction, the key parameters are checked and calculated.
