Damage of Reinforced Earth Retaining Wall Structure located in High Embankment
Session H_Poster Presentation
In Korea, the structure is mostly located on the upper part of the high embankment considering the geographical conditions at the time of expressway construction. Embankment was managed stepwise compaction according to height, but creep settlement of embankment itself may negatively affect superstructure. Reinforced earth retaining walls, which were recognized as flexible structures, were no exception to such geographical conditions. Especially, in the case of reinforced earth retaining wall located on abutment wing wall, damage due to differential settlement supported by pile, damage due to differential settlement and uneven settlement of reinforced earth retaining wall itself was frequently occurred. Therefore, in this study, the damage of reinforced earth retaining wall structure located on the high toe part was analyzed based on case. These data will be used as basic data for future maintenance.
