Seabed seismic wave test equipment and method

The invention relates to seabed seismic wave test equipment and method, the seabed seismic wave test equipment comprises a base, a detection mechanism, a penetration mechanism, an excitation mechanism and a control system, the base is placed on a seabed, the detection mechanism comprises a probe rod, a static sounding probe, a data acquisition recorder, a wave velocity tester and a plurality of detectors, the detectors are cylindrical and are coaxially mounted in the probe rod, and the probe rod is arranged on the control system. The plurality of detectors are respectively mounted at different height positions of the probe rod, the detectors are in communication connection with the wave velocity tester, the static sounding probe is coaxially mounted at the bottom end of the probe rod and is in communication connection with the data acquisition recorder, and the wave velocity tester and the data acquisition recorder are both in communication connection with the control system; the penetration mechanism is moun
