The invention provides a forged piece rough machining structure design method, a disc-shaft integrated forged piece and a labyrinth disc forged piece, the forged piece is used for machining and manufacturing parts of aerospace equipment, and the forged piece rough machining structure design method comprises the steps that S1, a step structure with an ultrasonic detection blind area on the forged piece is recognized; s2, dividing the step structure into a first step surface and a second step surface; and S3, designing the joint of the first step surface and the second step surface into a fillet, wherein the fillet can reduce the ultrasonic detection blind area. Therefore, the ultrasonic detection blind area in the forging step structure can be reduced, the fillet surface can ensure that the ultrasonic incidence direction is perpendicular to the streamline as much as possible, and the defect detection rate is increased; meanwhile, the design method can reduce the forging allowance, improve the material utilizat
