CBR Test in Geosynthetics with Confined Support Using Sands

The use of geotubes has become frequent in Geotechnical Engineering and, in terms of analysis, the main efforts applied in this field are based on the techniques of creeping, strengthing and also the drilling whose purpose is to analyze the material resistance in the puncture by taking the CBR test. This paper is focused on evaluating tension and deformation caused in the material which is practically found confined, allowing a better understanding about its behavior during the process. The results from this application have showed that tension and deformation are inversely proportional to the soil density condition. The main objective is to understand how confinement can change the geotubes design.
