Geosynthetics Committee : Case Studies Requested

The “Geosynthetics for Geohazard Mitigation Committee” as one of the Technical Committees for AGHP has created a task group named “Projects History”. This task group is collecting state-of-the- art case studies of projects on which Reinforced Soil Structures have been used to mitigate rockfall or other types of Geohazards. The purpose is to help educate members of the association and other professionals about the design procedures and implementation techniques. It is planned that this catalogue of projects will be easily accessible to industry professionals and become a valuable resource.

In an attempt to standardized data collection, the Technical Committee will be collecting information for each project as follows:

  • Problem: Description of the project, (Location, Country, Year of construction, Need for protection against Rockfall)
  • Design Process: What steps were taken during the design process? What various solutions were considered outside of geosynthetics?
  • Solution: Description of the applied system: Retaining / Catchment Structure / Earthen Barriers / Buried Infrastructure /Active/Pinned surface protections
    • The geometry of the structure: Height, Inclination, Width
    • Code used for design
    • Expected max. diameter of rock, bounce height, impact energy
    • Components of the applied system: Type of reinforcing material: polymeric. Steel, uniaxial, biaxial, tensile strength in MD/CMD, Dimensions of overlaps between panels / strips/ Netting / Anchors / Ropes, etc.
    • Installation: Sequence of installation
  • Results: Was the final project realized as oringially intended? What were the positives and negatives of the design and implementation process? How has the structure performed?
  • Long-term Performance: Is possible to receive updates on long-term performance of the structure?

The technical committee will be accepting a maximum of 2 case studies per organization for recognition in 2022. The case studies should be emailed to Co-chairs of the TC with the below address before April 15th,2022. Alternatively, you can submit a case study via this online form.
