Effect of fabric method on instability behavior of granular material

It is well known that the specimen preparation method and the resulting sand fabric significantly affect sand behavior and sand liquefaction resistance. In many cases, the fabric and behavior of reconstituted sand samples do not represent those of in-situ deposits. Therefore, understanding the influ...

Description
Summary:It is well known that the specimen preparation method and the resulting sand fabric significantly affect sand behavior and sand liquefaction resistance. In many cases, the fabric and behavior of reconstituted sand samples do not represent those of in-situ deposits. Therefore, understanding the influence of specimen preparation and sand fabric on its behavior, particularly at the critical state, is important for relating the behavior of laboratory reconstituted specimens to in-situ soil response. In this study, the effect of sand fabric and specimen preparation method on the shearing behavior of sand is studied using triaxial shear tests. Dry funnel pluviation (DFP) and wet tamping (WT) are used to prepare the specimens. The results from instability lines and stress–strain curves indicate that the liquefaction resistance of specimens prepared with the DFP method is more than specimens reconstituted by the WT method.
