The invention discloses a submarine sediment acoustic in-situ measurement device and method, and belongs to the field of submarine sediment acoustic in-situ measurement, and the submarine sediment acoustic in-situ measurement device comprises a main frame, a lifting type measurement sampling mechanism integrated in the main frame, and an obstacle crossing type walking mechanism arranged at the bottom end of the main frame, the obstacle crossing type walking mechanism comprises split type elastic telescopic wheels rotationally arranged at the four corners of the bottom end of the main frame, each split type elastic telescopic wheel comprises a hub motor, a rotating cylinder connected with the output end of the hub motor, an elastic unit and an arc-shaped wheel unit, the elastic units and the arc-shaped wheel units are arranged in the rotating cylinders, and mode switching units are arranged between the elastic units and the arc-shaped wheels. The switching mechanism is used for switching the split type elastic telescopic wheel to walk in an obstacle crossing walking mode or a flat ground walking mode; the drum is rotationally connected with the bottom end of the main frame. According to the acoustic in-situ measurement device and method for the seabed sediments, the obstacle crossing type walking mechanism is arranged, so that walking on the uneven seabed is realized, the measurement range is widened, and the measurement efficiency is improved.
