State of the Practice: Past, Current, and Future Perspectives of Reinforced Soil Retaining Structures in Turkey

This chapter describes how the concept of reinforced soil was first applied in Turkey with the Web-Soil and reinforced earth technologies. These types of modern technologies were mainly introduced to Turkish engineers through highway construction, which began as early as the 1970s, but got extensive during the 1980s. The technology, approved by the Turkish Highway Administration and observed by other engineers as being successful and economical, found itself application opportunities in other construction areas. Geosynthetic reinforcements were introduced in the construction of reinforced slopes with the overwrap technique and both geotextiles and geogrids were used as reinforcing elements for reinforced slope projects. Most of the applications were used on projects where public visibility was not possible, but there are a few exceptions. An experimental wall, built in 1993, was the first geosynthetic wall where the backfill consisted of lime treated clay. The objective of that wall was to investigate the replacement of granular material with an improved cohesive backfill with emphasis on real measurements and field behavior observations. The first segmented retaining wall was constructed during the summer of 1997 and it was a project realized for the Highway Administration. It was used to elevate an existing road over a tunnel portal. Generally, the wall was a stepping stone for further progress with such technology in Turkey. It is expected that many similar walls will be constructed in the same manner in the near future. A brief summary for every technique used and the improvements made in the area are described in detail in the following sections of the chapter.
