The invention discloses a wave-induced liquefied soil particle motion test device, which comprises a test mechanism, and the test mechanism comprises a first test tank filled with test water and a second test tank filled with test soil; the wave making mechanism is arranged on one side of the testing mechanism and used for making simulated waves; and the detection mechanism is partially arranged in the second test tank and is used for detecting the liquefaction depth of the test soil and calculating the movement speed of the test soil. The wave making mechanism designed by the test device can realize three wave making modes of horizontal pushing or rotary swinging and synchronous realization of horizontal pushing and rotary swinging, so that irregular movement of sea waves is simulated to the greatest extent, and the test environment is closer to the real environment. According to the test method, the test soil formed by mixing the soil particles and the tracer particles is adopted, the position change image
