Retaining walls are rigid structures
built to support the natural or back filling soils at different elevations.
Although the type of walls is generally composed of RC walls or gravity stone
walls, geosynthetic reinforced wall systems are also frequently preferred in
recent years. Geosynthetic reinforced walls are defined as a composite wall
system constructed by mechanically compacting the geosynthetic reinforcement
material placed between the back filling soil layers behind the wall. In this
presented study, applications that are designed to strengthen and to increase
the stability of a damaged high geosynthetic reinforced wall that was built in
two stages are described. Within the scope of the study, a new RC retaining
wall with piles and buttresses was designed in front of the lower part of the
existing geosynthetic reinforced wall. Plaxis 2D and 3D finite element analysis
software were used to determine the increment at the stability of the existing
retaining system and to calculate the displacements of the current wall.
Eleven-earthquake records were studied in accordance with Turkish Earthquake
Building Code-2018 in order to calculate the stability, the displacements, and
the internal forces of the piles under the foundation of newly designed
reinforced concrete retaining wall. This study is expected to be a useful tool
to reveal the parameters that should be taken into consideration in the seismic
performance of the retaining walls that are going to be constructed to strengthen
an existing retaining structure.
