The invention relates to a blast furnace distribution chute and a design and analysis method thereof. The blast furnace distribution chute comprises a chute body 1, guide rails 2 arranged on two sides of the upper part of the chute body 1, and an axial baffle plate 3; the chute body 1 forms a chute way consisting of wall plates on two sides and a bottom surface; the bottom surface of the chute body 1 consists of a large arc concave surface 14, a small arc convex surface 12 and an arc conical surface 11 connected in sequence in the material flowing direction; and at least two arc stop ribs 13 are arranged on one side, near the small arc convex surface 12, of the large arc concave surface 14. A discrete element method is adopted to simulate to analyze the material current collecting characteristics to design and adjust a chute shape of the blast furnace distribution chute and a rib distribution scheme, so that a full-covered pad is formed in a material current impact area in the chute way during distributing, the blast furnace distribution chute with prominent beating and grinding effects is finally designed, the impact and the wear of the blast furnace distribution chute by material currents can be effectively relieved, and the service life of the blast furnace distribution chute is prolonged.
