Zusammenfassung:	An airtight closed vacuum preloading model barrel device based on flange connection comprises a barrel body and an annular cover plate, a soil body is arranged in the barrel body, and geotechnical cloth covers the soil body; the upper end opening of the barrel body and the cover plate are of a flange connection structure, the upper end opening of the barrel body is covered with a vacuum film, andthe outer edge of the vacuum film is pressed between the cover plate and the flange. A vacuum pipeline interface, a pore water pressure sensor hole and a vacuum meter hole are formed in the upper wallsurface of the barrel body in a penetrating manner; a drainage plate is vertically buried in the soil body and is connected with the vacuumizing system through a vacuum pipeline; rubber plugs are arranged in the pore water pressure sensor hole and the vacuum meter hole respectively, thin holes are formed in the rubber plugs in a penetrating mode, and micro pore water pressure sensors and vacuum meter pipes are inserted in
