The present application provides a kind of highway tunnel fabricated steel structure-concrete thin-walled type reinforcing structure, including multiple groups of support structure, multiple groups of support structure are sequentially connected along the length direction of tunnel, support structure includes: two groups of fixed base, respectively set in the bottom wall both sides of tunnel;Two groups of duct piece structure, symmetrically set in the top wall both sides of tunnel, duct piece structure includes thin-walled duct piece and the support duct piece connected to the upper and lower ends of thin-walled duct piece, the thickness of thin-walled duct piece is less than the thickness of support duct piece, the support duct piece located in the lower end of thin-walled duct piece is connected with the top of fixed base on the same side, and the distal ends of two support duct pieces located in the upper end of thin-walled duct piece are connected with each other.The present application also provides a kind of design method of highway tunnel fabricated steel structure-concrete thin-walled type reinforcing structure.Thin-walled duct piece is treated with hierarchical stepped thin-walled, which can ensure that the construction limit of highway tunnel is not affected by reinforcement, and provides sufficient clearance for large vehicles to pass through the tunnel.
