The utility model discloses a large-span frame bridge passing through a subway tunnel. The large-span frame bridge comprises a counterweight chamber, the counterweight chamber is divided by two adjacent side walls and is symmetrically positioned between the motor vehicle lane and the non-motor vehicle lane; and after the counterweight chamber is filled with the iron ingots, the total weight of the iron ingots is equal to the total weight of soil excavated and unloaded above the subway tunnel below in the subsequent jacking construction process. The frame bridge has the advantages that the long and narrow counterweight chambers are uniformly and symmetrically arranged in the frame bridge for stacking the iron ingots, so that the unloading of the frame bridge to the existing subway tunnel is basically zero in the jacking process of the frame bridge, and the iron ingots in the counterweight chambers are permanently stacked, so that the subway tunnel below is protected to the greatest extent; and stacking of the
