在岩石TBM设计中，全断面岩石隧道掘进机（TBM）盘形滚刀的布置设计是关键技术之一。但由于种种原因，在文献中发表的论文很少。本文根据工程技术要求和相应的刀盘结构设计要求，提出了复杂约束条件下的非线性多目标盘形刀具布局数学模型及相应的多阶段求解策略，将整个盘形刀具布局设计过程分解为盘形刀具间距设计和盘形刀具平面布局设计。采用基于有限元理论的数值模拟方法，对3个TBM圆盘滚刀引起的岩石破碎过程进行模拟，确定最佳滚刀间距。采用协作协同进化遗传算法（CCGA）来解决圆盘铣刀的平面布局设计问题。最后给出了TBM盘形滚刀布置设计实例，验证了该方法的可行性和有效性。计算结果表明，该方法可以解决TBM圆盘滚刀的布置设计问题，并在短时间内提供多种布置方案供工程师选择。
In rock TBM design the disc cutters’ layout design of the full-face rock tunnel boring machine (TBM) is one of the key technologies. However, there are few published papers in literatures for various reasons. In this paper, based on the engineering technical requirements and the corresponding cutter head’s structure design requirements, a nonlinear multi-objective disc cutters’ layout mathematical model with complex constraints and the corresponding multi-stage solution strategy are presented, in which the whole disc cutters’ layout design process is decomposed into the disc cutters’ spacing design and the disc cutters’ plane layout design. A numerical simulation method based on the FEM theory is adopted to simulate the rock chipping process induced by three TBM disc cutters to determine the optimal cutter spacing. And a cooperative coevolutionary genetic algorithm (CCGA) is adopted to solve the disc cutters’ plane layout design problem. Finally, a disc cutters’ layout design instance of the TBM is presented to demonstrate the feasibility and effectiveness of the proposed method. The computational results show that the proposed method can be used to solve the disc cutters’ layout design problem of the TBM and provide various layout schemes within short running times for the engineers to choose from.
