The invention relates to a saturated soft soil vibration centrifugal infiltration instrument. The saturated soft soil vibration centrifugal infiltration instrument comprises a support (23), a vibration platform (18), a glass scale rotating barrel (66), a rotating motor (60) fixed to the vibration platform (18) and a water injection part. The vibration platform is controlled by a first loading control table to do vibration in the horizontal direction and controlled by a second loading control table to do vibration in the vertical direction. The glass scale rotating barrel (66) comprises a barrel wall with scales, large hollow cylindrical water-permeable stone (20) and small hollow cylindrical water-permeable stone (8), wherein the large hollow cylindrical water-permeable stone (20) and the small hollow cylindrical water-permeable stone (8) are coaxial, and the glass scale rotating barrel (66) is made of water-permeable concrete. A motor rotating shaft (4) of the rotating motor (60) is arranged in the middle of the glass scale rotating barrel (66) and stretches out of the bottom of the barrel. A soil sample trough (9) is formed between the inner wall of each large hollow cylindrical water-permeable stone (20) and the outer wall of the corresponding small hollow cylindrical water-permeable stone (8), and filter paper (6) is attached to the inner wall of each soil sample trough (9). The saturated soft soil vibration centrifugal infiltration instrument can simulate the soft soil infiltration and solidification characteristics under the load effect more accurately.
