Geofoam Grade-Raising Fill Above Geogrid-Reinforced Soil Wall

Yalıçiftlik – Bodrum / Muğla

Site Conditions

  • Construction of terrace garden areas in front of near-vertical rock slopes using wrap-around faced, geogrid-reinforced soil wall technology.
  • Because the reinforced soil wall facing was inclined at a flatter angle than the adjacent rock slope, the available space became insufficient to install the geogrid reinforcement at the required design length above a certain wall elevation.
  • Continuing construction of the reinforced soil wall with geogrid lengths shorter than the design requirements would have resulted in internal stability problems.

Designed Solution

  • Continuation of the fill construction using geofoam block technology at elevations where the geogrid reinforcement could no longer be installed at the required design length.
  • Implementation of a hybrid solution combining two different geotechnical technologies.

Advantages of the Applied Geotechnology

  • The fill could be constructed up to the required project elevations without introducing additional stresses that would adversely affect the internal stability of the geogrid-reinforced soil wall.
