The invention belongs to the technical field of bridge engineering, and particularly relates to a cable-stayed bridge concrete door type cable bent tower stiffening structure which comprises two symmetrically-arranged tower columns, a bearing platform fixedly connected to the bottom ends of the tower columns, a pier column fixedly connected to the bottom end of the bearing platform, a fixing part fixedly connected to the bottom end of the pier column and fixed to the ground, and a bearing part fixedly connected between the two tower columns. A bridge is erected at the top end of the bearing part, horizontally-arranged upper cross beams are fixedly connected between the top ends of the two tower columns, and stiffening structures are arranged between the two ends of the tower columns and the two upper cross beams. The cable-stayed bridge overcomes the defects that in a traditional cable-stayed bridge, vertical prestress is arranged in a tower column to improve stress, consequently, the internal structure of th
