ABSTRACT
The construction of geosynthetic-reinforced soil retaining walls with a staged-constructed full-height rigid facing for railways, including high-speed train lines, roads and other retaining walls began to be used in Japan in the late 1980s. After the wrap-around type geosynthetic reinforced soil wall is constructed, the front face is covered by a cast-in-situ reinforced concrete wall. The earthquake performance of these walls is extremely high and is economical compared to classical retaining structures. This system was used in a slightly different way on the reinforced concrete wall of an industrial building in Bursa, a city located in the first degree seismic zone of Turkey. The 10m high reinforced concrete wall was staged-constructed in three parts using the prefabricated modular double-wall system, while the backfill was reinforced with geogrids. In this paper, the effect of using a geogrid-reinforced fill and unreinforced fill on the calculation of the reinforced concrete wall section is compared, and the details of the system and its construction are discussed.
