<P>PROBLEM TO BE SOLVED: To provide a reinforcement method for a bridge abutment capable of ensuring the prevention of the bridge abutment damage which has a generating mechanism as follows: in the bridge in which the bridge abutment and a bridge girder are connected with a rigid-framed structure and a back fill is placed in the back side of the bridge abutment, when the back side of the bridge abutment is reinforced by a reinforcement means, temperature change and an earthquake or the like deform a bridge girder, and apply excessive bending tensile load to the back side of the bridge abutment through the bridge girder. <P>SOLUTION: In the bridge in which the bridge abutment 2 and bridge girder 5 are connected with a rigid-framed structure and a back fill 6 is placed in the back side of the bridge abutment 2, the back side of the bridge abutment 2 is reinforced with a reinforcement means, the reinforcement means being formed in such a way that, in the back side of the bridge abutment 2, steel members 10 are inserted into holes 9 which are formed across the height direction of the bridge abutment 2 and at intervals in the width direction of the bridge abutment 2, and then grout material is injected into the holes 9. <P>COPYRIGHT: (C)2012,JPO&INPIT |
