Module 4.B – Geosynthetically Reinforced (or Confined) Soil Concepts (1.0 PDH Credit) by Colby Barrett
Using tensile inclusions to reinforce soil is a technology that goes back at least 3000 years. However, it was only in the last thirty years that this technology has found widespread acceptance and adoption in the United States. In this training model, you will learn the history of reinforced soil and how it diverged into two similar – but functionally distinct – technologies: traditional Mechanically Stabilized Earth (MSE) and Geosynthetically Reinforced (or Confined) Soil (GRS/GCS). The differences between the two design methodologies will be presented both in concept, triaxial soils testing analogies, and by examining full scale tests performed by the Federal Highway Administration. Design guidelines for GRS/GCS will be introduced followed by pictures of GRS/GCS applications including integral bridge system abutments, retaining walls, rockfall barriers and catchments, avalanche and debris flow barriers and deflectors, and structures to rebuild roadway width lost during landslide events. Throughout the module, the impressive performance of state-of-the-art GRS/GCS is highlighted and contrasted with the shortcoming of state-of-the-practice MSE technology.
