The invention provides a movable door device for measuring the soil arching effect of overlapped tunnels and a test method. The movable door device comprises a box body, a movable door, a tunnel modeland a three-dimensional scanner. The movable door is horizontally arranged in the box body, a plurality of soil pressure boxes are arranged on the movable door, a space defined by the upper surface of the movable door and the box body is used for containing a soil body, and the tunnel model is arranged in the soil body. The movable door can move. The movable door moves to enable the soil body tocollapse, and the soil pressure box can measure the vertical soil pressure of the soil body. The three-dimensional scanner is arranged in the box body and located below the movable door, and the three-dimensional scanner can measure the arch axis of the soil body forming the soil arch effect. By means of the movable door device and the test method, the soil arching effect generated by the spaces with different widths of th
