摘　　要：刀盘设计是全断面岩石隧道掘进机的设计关键,是影响其掘进性能的决定性因素。综述了刀盘设计关键技术的研究进展,重点对盘形滚刀破岩机理、刀盘切削参数、围岩力学属性参数及试验、刀具破岩受力分析模型和施工预测模型、刀盘布局(含刀具布置)等方面进行了较系统的分析和总结。最后讨论了有待深入研究的问题。Being a crucial factor in influencing the performance of full face rock TBM, the cutterhead design is one of the key issues of TBM. The researches and applications on the key technologies of the cutterhead design were presented, which mainly included rock fragmentation process mechanism by disc cutter, cutting geometry, rock mechanical properties and testing, disc cutter cutting force and performance prediction model,cutterhead layout and cutter allocation, etc. Finally, the further research issues of cutterhead design in the future were proposed.
