An ultra-large horizontal seepage test system with intelligent graded loading and variable seepage path is provided, which includes a water storage system, a water pressure system, a horizontal seepage test system and an intelligent loading and control system. The water storage system, the water pressure system and the horizontal seepage test system are connected in sequence, and the water pressure system is used to apply a water pressure and a vertical pressure to a test piece to be tested in the horizontal seepage test system. An outlet valve of the horizontal seepage test system is connected to the water storage system, and the intelligent loading and control system is used to control operations of electrical components of the water pressure system and the horizontal seepage test system. With the test system, a water head pressure can be loaded intelligently, and an infiltration angle of water inflow can be adjusted.
