The invention relates to an underwater explosion test device for fracture lumpiness and shock wave characteristic analysis, which comprises a test pool, a drainage system, a fixing device for mounting a plate and a movable gantry crane, a lumpiness extraction device is fixed at the bottom of the fixing device, and an underwater shock wave sensor and an explosive are mounted on the fixing device; the underwater shock wave sensor, the explosive and the center of the plate are located at the same height, and wave absorbing systems are arranged on the inner and outer sides of the wall of the test pool. The fixing device is directly lifted out of the water surface and placed on the ground surface through the movable gantry crane, the plates can be directly replaced under the condition that water in a test pool is not emptied, the test convenience is greatly improved, the attachment layer is adopted to absorb or restrain and reflect explosive shock wave loads, the free field environment of the test is achieved to t
