PROBLEM TO BE SOLVED: To provide a method of seismically reinforcing a bridge, which enables mounting of an anchor bolt for suspending a seismically reinforcing material to be mounted on a pier even on a hollow floor slab whose cylindrical form interior for recess forming is a cavity. SOLUTION: According to the method, a hole 18a is bored in a hollow form which is embedded for forming a hollow floor slab 9 and has an end thereof blocked, from outside the floor slab, and a packer 19 in a squeezed state is inserted into the hollow form via the hole 18a and inflated, for partitioning the interior of the hollow form at a location spaced a predetermined distance away from the blocked end, to thereby define a partitioned space in the hollow form. Then an injection pipe 20 is inserted via the hole to inject mortar 22 into the partitioned space by the injection pipe 20, and at least a lower half space portion of the hollow form is filled wit the mortar 22, whereby the mortar 22 serves as an anchor bearing base for mounting the seismically reinforcing material.
