为解决盾构施工中全断面隧道掘进机（TBM）滚刀贯入度的预测问题，使其更好地应用于所处地层，依托深圳地铁6号线的相关数据及中铁TBM云管理平台的数据处理功能，定性分析TBM破岩过程，并将破岩的宏观过程划分为3个阶段；采用线性回归方法，依次从贯入度与掘进推力的关系、贯入度与刀盘转矩的关系对TBM滚刀贯入度的变化情况进行量化分析，并在这一过程中推导得到TBM掘进的贯入度与推力、转矩的参数预测模型，并结合现场实测结果对线性回归法的预测结果进行验证。结果表明： 1）TBM在不同阶段的贯入度、推力及转矩均有不同程度的变化，且相互之间存在一定的关联； 2）掘进参数的线性回归预测模型经过验证是合理的，表明线性回归法适用于TBM掘进参数的预测，可视具体情况为隧道工程实施阶段掘进参数的调整提供理论指导和参考。

The penetration prediction of disc cutter of fullface tunnel boring machine (TBM) is conducted. The rockbreaking process of TBM is qualitatively analyzed based on relevant data of Shenzhen metro line 6 and the data processing function of TBM cloud management platform, and as well it is divided into three stages macroscopically. The linear regression method is used to quantitatively analyze the change of penetration of TBM disc cutter in terms of the relationship between penetration and driving thrust, and the relationship between penetration and cutterhead torque. In this process, the parameter prediction model of penetration, thrust, and torque of TBM driving is derived, and the prediction results of linear regression method are verified by the field measurement results. The results show that: (1) The penetration, thrust, and torque of TBM vary in different stages, and there is a certain correlation among them. (2) The linear regression prediction model of tunneling parameters is verified to be reasonable, which shows that the linear regression method is suitable for the prediction of TBM tunneling parameters, and can provide theoretical basis and reference for the adjustment of tunneling parameters in the implementation stage of tunnel.
