The invention provides a pseudo-dynamic experimental method, and belongs to the field of tunnel engineering. The pseudo-dynamic experimental method adopts a tunnel model experimental device, and comprises the following steps of a, opening a first side plate, and putting a stratigraphic simulating material into a cavity; b, putting an underground structural model into the cavity; c, putting the stratigraphic simulating material into the cavity, and making the stratigraphic simulating material cover the underground structural model; d, fixing the tunnel model experimental device on the ground, and making the first side plate of the tunnel model experimental device upward; e, inputting a displacement load at one end where the first side plate is located. By using the pseudo-dynamic experimental method, the limitation that a conventional pseudo-dynamic experimental method can be only carried out through an on-line method is broken through; various defects of an on-line experiment are avoided. In addition, the pseudo-dynamic experimental method can be used for carrying out dynamic analysis without needing a vibrating table; the equipment requirement on a laboratory is lowered; the experimental cost is also greatly saved.
