The invention belongs to the technical field of civil engineering, and discloses a large-scale steel bar grouping and discharging optimization method and device. The method comprises the steps of defining a first variable set, creating a first mathematical model, inputting to-be-blanked steel bars, and acquiring a first steel bar data combination and remaining blanked steel bars; defining a secondvariable set and a third variable set; establishing a second mathematical model and a third mathematical model, dividing the residual steel bar matrix into a first residual steel bar matrix and a second residual steel bar matrix according to a threshold; obtaining a plurality of sub-matrixes A or a plurality of sub-matrixes B through large-scale steel bar grouping, inputting the plurality of sub-matrixes A and the raw materials into the second mathematical model to obtain a second steel bar data combination, and inputting the plurality of sub-matrixes B and the raw materials into the third mathematical model to obtai
