The invention discloses a tunnel vertical displacement monitoring device and a continuous monitoring method, and belongs to the technical field of tunnel construction. The two ends of the spring are connected with the two force transmission plates respectively; one end of the force transmission rod is connected with the bottom of one force transmission plate; the vibrating wire type pressure box is connected with the top of the force transmission plate far away from the force transmission rod; the dowel bar, the force transmission plate, the spring and the vibrating wire type pressure box are all located in the settlement monitoring hole, and the end, away from the force transmission plate, of the dowel bar is connected with the bottom of the settlement monitoring hole. The tunnel vertical displacement monitoring device is convenient to install, multiple in measuring point, small in drilling hole and small in stress release, disturbance to tunnel base surrounding rock can be effectively reduced, base settleme
