Abstract: Disclosed in the present invention is a water filling and drainage test device and method for a prefabricated crack-containing reinforced concrete lining pressure tunnel. The test device comprises a cylindrical barrel, a reinforced concrete lining containing prefabricated cracks, surrounding rock, geotechnical cloth, a front flange, a rear flange, and a monitoring instrument. The surrounding rock is proximate to an inner wall of the cylindrical barrel, and the reinforced concrete lining containing the prefabricated cracks is inside of the surrounding rock; and the front flange and the rear flange are fixed at two ends of the cylindrical barrel. The test device is used for carrying out a water filling and drainage test on the pressure tunnel, and observing the change in the width of the prefabricated cracks and the conditions of the pressure tunnel.
