【Abstract】 A cutter layout method of the full-face rock TBM was proposed,in which the technological 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 design,the experimental results show that the proposed cutter layout mathematical model and corresponding solution strategy are feasible and effective.更多还原
