摘要： 刀盘是全断面岩石掘进机的关键核心部件。全断面岩石掘进机作业过程中，刀盘形变理论是完善其设计和应用技术的基础。充分考虑盘形滚刀在刀盘上的布置规律及刀盘与全断面岩石掘进机主机的联结关系，以中心滚刀与刀盘联结为一体而可看作无孔盘体或有间隙盘体的客观特点为根据，建立了中心无孔刀盘和中心有孔刀盘理论模型，并分别提出了刀盘形变的一体化计算理论和分域计算理论。最后应用所提理论于某工程全断面岩石掘进机刀盘形变量计算，并与数字加载模拟结果进行对比。研究发现，分域计算理论在支撑域内的结果与模拟值较一致；而在支撑域外，一体化计算理论和分域计算理论值的均值或分域计算理论值的58%与一体化计算理论值的42%的和与模拟值较一致。所提方法与所建理论为完善全断面岩石掘进机刀盘设计理论和应用技术提供了借鉴。

Abstract: The cutterhead is the key core component of the full face rock tunnel boring machine (TBM). In the process of TBM operation, the theory of cutterhead deformation is the basis for improving its design and application technology. The arrangement pattern of disc cutters on the cutterhead and the connection relationship between the cutterhead and the main body of the full-face rock tunnel boring machine are thoroughly considered. Based on the objective characteristic that the central cutters are integrated with the cutterhead and can be regarded as either a solid disc body without holes or a disc body with clearance, theoretical models for both the solid-center and hollow-center cutterheads have been established. Furthermore, the research has proposed unified calculation theories for the deformation of the cutterhead as well as subdomain calculation theories. Finally, the theories proposed were applied to calculate the deformation of the cutterhead for a full face rock tunnel boring machine in a specific engineering project, and the results were compared with those from digital loading simulations. It was found that the results from the subdomain calculation theory are in good agreement with the simulated values within the support domain. Outside the support domain, the average of the values from the integrated calculation theory and the subdomain calculation theory, or a combination of 58% of the subdomain calculation theory value with 42% of the integrated calculation theory value, shows good consistency with the simulated values. The methodologies and theories presented in the text offer insights for the refinement of the design theory and application techniques for the cutterhead of a full face rock tunnel boring machine.
