为分析TBM硬岩掘进时刀盘分区滚刀的磨损规律，以文登抽水蓄能电站排水廊道TBM硬岩掘进滚刀磨损数据为例，通过对滚刀运动形式的分析，研究中心滚刀异常磨损机制，建立基于掘进参数的滚刀磨损量预测模型。研究结果表明： 1)硬岩掘进过程中刀盘在最大推力作用下无法有效破岩，滚刀半径与安装半径不协调造成中心滚刀区域异常磨损； 2)提出的滚刀磨损预测模型可准确反映出掘进参数、掘进进尺和安装半径的综合影响。

To explore the disc cutter wear patterns of tunnel boring machine (TBM) in hard rock, a case study is conducted on the Wendeng pumped storage hydropower station. The disc cutter wear data of the case study is collected, based on which, abnormal wear mechanization of center cutter is examined through cutter motion analysis, and a prediction model for cutter wear based on tunneling parameters is established. The results reveal the following: (1) The cutterhead cannot break the rock effectively under the maximum thrust in hard rock tunneling, and abnormal wear of central disc cutter occurs due to disharmony between the cutter radius and the installation radius. (2) The proposed wear prediction model accurately reflects the comprehensive impact of tunneling parameters tunneling length, and installation radius.
