The invention discloses a reverse construction method for a frame bridge. The reverse construction method comprises the following steps of (1) foundation construction, (2) straight wall construction, (3) excavation of a top plate foundation pit, (4) top plate construction, (5) soil body excavation, and (6) bottom plate construction. The reverse construction method for the frame bridge adopts the mode that a straight wall is construction firstly, then a top plate is constructed, and finally a bottom plate is constructed, the supporting function of soil bodies is ingeniously used, and the number of extra erected supports is effectively decreased; and meanwhile, large-area foundation pit excavation in an original construction method is avoided, the construction process is simplified, the construction period is short, the project manufacturing cost is greatly lowered, the influences on traffic of a construction site are small, and the method has good social and economic benefits in construction of down through frame bridges.
