Dragging type surface wave detection device and method for high-filled embankment

The invention discloses a dragging type surface wave detection device and method for a high-filled embankment. The device comprises a shell, a battery, a seismic source excitation assembly, a moving assembly, a detector module and a control system. The battery is mounted at the top of the shell; the detector module comprises N detectors, N is greater than or equal to 5, the N detectors are distributed in a cross shape to form a cross-shaped detector array, the interval distances of the detectors located on the same straight line in the cross-shaped detector array are the same, and the front end, the rear end, the left end and the right end of the cross-shaped detector array are provided with the same number of detectors; an extension line from the rear end to the front end of the cross-shaped detector array is parallel to the bottom surface of the shell; the seismic source module comprises two hammering seismic sources and a motor, and the two hammering seismic sources are respectively arranged in front of an
