The invention relates to the technical field of tunnel construction, in particular to a large-section tunnel lagging jack supporting structure which comprises a plurality of lagging jack sections, and two mounting rings are fixedly connected to the ends, close to each other, of every two adjacent lagging jack sections. The mounting rings are located on the two sides of the ends of the arch frame sections, the two mounting rings are located on the sides close to the inner arc faces of the arch frame sections at the same time, a rotating column is arranged between every two adjacent arch frame sections, the rotating columns penetrate through the mounting rings, are coaxially arranged with the mounting rings and are rotationally connected with the mounting rings, and fixing pieces used for limiting the positions of the mounting rings on the rotating columns are arranged on the rotating columns. An arc-shaped connecting pipe is arranged between every two adjacent arch frame sections, the arc-shaped connecting pip
