The invention discloses a curved-surface-shaped concrete faced rockfill dam and a construction method thereof. According to the curved-surface-shaped concrete faced rockfill dam and the construction method thereof, a face plate in the middle of an upstream dam slope is a curved-surface-shaped protrusion, the spectacular momentum of the dam is manifested, and the appearance is attractive; a protruding face plate arranged in the face plate pressing joint areas can apply pre-pressure to the tension joint areas on the two sides, a connecting plate is arranged on the bottom surface between the slabjoints of the face plate of tension joint areas of the dam on the two sides, so that cracking of the slab joints of the tension joint areas is avoided; a semi-rigid mixture cushion layer is lined below the whole face plate, so that the stress condition of the face plate is improved; an arc hinge is arranged between the plate seat and the face plate, so that the stress of the face plate structureat the position is facilit
