Summary:A large-span heavy-load stress induced type backfill open cut tunnel lining structure enables open cut tunnels to have large span and bear large load and can effectively control design thickness of open cut tunnel linings, and construction quality of the open cut tunnel linings is easy to control. Arc portions (11), side walls (12) and inverted arches (13) which are constructed by concrete or reinforced concrete together form the open cut tunnel linings (10) with annular cross sections, and stress induced protection arches (20) are arranged on arc surfaces of outer contours of the arc portions (11) and the side walls (12) of the open cut tunnel linings (10).
