摘　　要：给出了全断面岩石掘进机的刀具布置设计方法,归纳出刀具布置的技术要求,并给出刀盘上不等刀间距的盘刀破岩量的估算方法。建立了带复杂性能约束的非线性多目标刀具布置优化模型,进而在该模型目标函数及其约束条件的耦合分析和解耦的基础上,给出刀具布置极径与极角计算的分阶段求解策略,并用演化算法进行了求解。以引进的某型号全断面岩石掘进机刀具布置问题为案例进行验证,并与原刀具布置设计方案进行对比,表明了该布置优化模型及其求解方法的可行性和有效性。A cutter layout method of the full--face rock TBM was proposed, in which the techno logical requirements of the cutter layout were summarized, then the rock-broken volume estimation method for the non--equality cutter space was given and a nonlinear multi--objective cutter layout mathematical model with complex constraints was established. Further, based on the coupling analysis of the multi--objectives and constraints of the mathematical model, a hierarchy solving strategy of polar radius and polar angle was given and the genetic algorithm （GA） was used to solve cutter layout design of the full--face rock TBM. Finally, taking some imported full--face rock TBM cutter layout design as an experimental example, compared with the computational results of the original layout de sign, the experimental results show that the proposed cutter layout mathematical model and corresponding solution strategy are feasible and effective.
