The invention discloses a reinforcing structure for a soil body above a shallow-buried tunnel and a construction method of the reinforcing structure, and relates to the field of tunnel engineering.The construction method comprises the steps that firstly, before tunnel construction, a reinforcing supporting device is arranged in a foundation on the lower side of a road; 2, a bearing platform is poured at the upper ends of the lime-soil compaction piles in the length direction of the tunnel, and a bottom cross beam is erected on the bearing platform; 3, main beams are erected on the bottom cross beams, and the main beams are connected with the lime-soil compaction piles; 4, static pressure compaction is conducted on the roadbed, then the road surface is poured, after the road surface is coagulated, beam plates are laid on the road surface, and the beam plates are connected with the main beams; 5, after tunnel construction is completed, the beam plates are dismantled, and the road surface is laid again through a
