The invention belongs to the field of geotechnical engineering tests, and relates to a tunnel seepage test device. The main structure comprises a model box, a front cover plate, a rear cover plate anda tunnel model, wherein the front surface of the model box is provided with the front cover plate, the back surface of the model box is provided with the rear cover plate, and the tunnel model with acircular structure is arranged between the front cover plate and the rear cover plate. Based on the test requirements, different water head heights and surrounding rock types are adjusted, the displacement of the blind pipe is controlled, the shape of the tunnel model is changed, the repeated utilization rate of the model box is increased, the front cover plate made of organic glass is convenientto use, and the test process and phenomenon are easy to observe. In the test process, water flow is collected and drained to the longitudinal blind pipes through the annular blind pipes and discharged out of the tunnel model t
