RTRI Develops and Puts into Practical Use Seismic Reinforcement Method for Bridge Abutments Using Ground Reinforcing Nails and Available Even in Narrow Places
The Railway Technical Research Institute (RTRI) developed a “seismic reinforcement method for bridge abutments using ground reinforcing nails” (Fig. 1) as an effective seismic reinforcement method which can be performed while minimizing the workspace in front side of bridge abutments. This method eliminates the need for extensive work starting from the front side of the abutment as in the past and enables economical design according to the required seismic performance levels.
