Abstract:A cutters layout method of the full-face rock TBM is proposed in this paper, in which the technology requirements of the cutters layout are summarized, then the rock-broken volume estimation method for the non-equality cutters space is given and a nonlinear multi-objective cutters layout mathematical model with complex constraints is 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 is given and physical programming is used to solve cutters layout design of the full-face rock TBM. Finally taking the some imported full-face rock TBM cutters layout design as an experimental example, compared with the computational results of the original layout design, the experimental results show that the proposed cutters layout mathematical model and corresponding solution strategy are feasible and effective.
