In order to optimize the tunneling performance of a shield cutterhead in a tunnel project, the mechanical performance of the cutterhead was checked on the basis of the study of the cutter arrangement rule. Finally, the hobbing arrangement was improved and optimized by genetic algorithm. The results show that the radial unbalance force of the cutterhead is reduced by 61.22%, the overturning moment is reduced by 87.49% and the broken rock amount variance is reduced by 9.8%, which achieves a better optimization effect. Provides the theoretical basis, has the important scientific significance and the engineering value to enhance the stress performance of the cutterhead and the service life of the cutter.
