<P>PROBLEM TO BE SOLVED: To provide a reinforcement method for a bridge abutment in an existing bridge capable of ensuring the prevention of the bridge abutment from damage which has a generating mechanism as follows: in the existing bridge in which the bridge abutment and a bridge girder are connected with a rigid-framed structure, when the bridge abutment is reinforced by a reinforcement means for dispersing the deformation load of a bridge girder applying to the bridge abutment, temperature change and an earthquake or the like deform a bridge girder, and applies excessive bending tensile load to the bridge abutment through the bridge girder. <P>SOLUTION: In the reinforcement method for the bridge abutment 1 in the existing bridge in which the bridge abutment 1 and a bridge girder 2 are connected with a rigid-framed structure, a portal column 3 is constructed on the ground around the outside of the bridge abutment 1 as a reinforcement means, and the end of the bridge girder 2 is fixed to the portal column 3, therefore the deformation load of the bridge girder 2 applied to the bridge abutment 1 is dispersed to the existing bridge abutment 1 and the portal column 3. <P>COPYRIGHT: (C)2012,JPO&INPIT |
