A Case Study: Shear Interface Testing of a Constructed Geosynthetic Barrier

Since geosynthetic interfaces often serve as a weak plane on which sliding may occur, shear strengths of these need to be carefully assessed. In this case study, and soil samples were exhumed from the base side slope constructed facility generate site specific data. The importance using representative materials performing interface testing under conditions similar those expected in field are discussed. Once test data was available, they used stability analysis software package determine Factor Safety (FoS) barrier system. Lastly, illustrate risk literature parameters without confirming them during construction, FoS actual will compared design strengths.
