The invention provides a bridge concrete slab staggering correction method. A long stepping bar of which the cross section is of a triangular shape is laid on a rear end panel of a next segment of template at the joint with a current segment of template; a height of an opposite side of the triangle is a lifting quantity of the current segment; a length of an inclined side of the triangle is in curve smooth transition with the bottom of the current segment. According to the bridge concrete slab staggering correction method provided by the invention, by laying the triangular stepping bar, due toexistence of the volume of the triangular stepping bar, the space at the bottom of the next segment is filled up, concrete is not poured at the position in the pouring process, the height of the rearend of the concrete of the next segment can be equal to that of the front end of the concrete of the current segment, and the concrete at the bottoms of two segments can be in smooth transition so asto avoid a slab staggering phenomenon. Therefore, manual chiseling of the slab staggering can be eliminated; when bridge construction cost is reduced, cracks and stress concentration which are generated for a bridge body due to chiseling and grinding can also be avoided; the bridge concrete slab staggering correction method is beneficial for improving quality of bridge engineering. Moreover, themethod is simple, feasible, low in construction difficulty and beneficial for improving construction efficiency.
