The invention provides a multifunctional train floor structure with heat insulation, moisture insulation, vibration reduction, noise reduction and sealing functions, which comprises a CFRP (carbon fiber reinforced plastic) plate 10, a vacuum layer 20, a rubber plate 30, a normal-pressure air layer 40, a draining plate 50, a wood plywood 60, floor cloth 70 and an elastic support frame 80, the CFRP plate 10, the vacuum layer 20, the rubber plate 30, the normal-pressure air layer 40, the draining plate 50, the wood plywood 60 and the floor cloth 70 are sequentially arranged from the outer side of the floor to the inner side of the floor. The elastic supporting frame 80 sequentially penetrates through the CFRP plate 10, the vacuum layer 20, the rubber plate 30, the normal-pressure air layer 40, the draining plate 50, the wood plywood 60 and the floor cloth 70 so that the CFRP plate 10, the vacuum layer 20, the rubber plate 30, the normal-pressure air layer 40, the draining plate 50, the wood plywood 60 and the floor cloth 70 can be connected. By means of the technical scheme, the technical problem that in the prior art, a floor structure is poor in noise reduction and isolation performance is solved.
