A seabed slope shaking table test system for simulating ocean wave action includes a rigid model box, a wave-generating equipment support, an integrated lifting wave device, and an end wave-damping device. The rigid model box is connected to the shaking table platform at its bottom. The wave-generating equipment support is fixed to the side wall of the rigid model box, supporting the integrated lifting wave device and adjusting its height. The integrated lifting wave device is used for wave simulation and reflected wave elimination. The end wave-damping device is fixed to the side wall of the rigid model box, opposite the integrated lifting wave device, and is used for end wave damping. This invention simulates earthquakes on the shaking table while simultaneously loading waves, unifying the effects of overlying seawater, waves, and earthquakes. This allows for a more realistic simulation of multi-dynamic coupling instability of seabed slopes in complex marine environments. Furthermore, the wave parameters and the water depth of the wave-generating equipment are flexibly adjustable, facilitating a wider range of experimental parameters for seabed slopes.
