Vibro Stone Columns | Ground Improvement | CivilDigital

Dec 10, 2017· Vibro Stone Columns. To improve the load bearing capacity of in-situ soils and fills, Vibro stone columns are designed and are used. These columns reduce the differential settlements of non-homogeneous and compressible soils which allows the use of shallow footings and thinner base slabs. For the construction of Vibro stone columns, the vibrator is made to reach the design …

Stone Column Method in Geo Engineering Projects

Stone columns carry more load than the surrounding soils due to their greater stiffness. Stress concentration ratio (ratio of stress carried by the column to that carried by the in-situ matrix soil) and area replacement ratio (ratio of column cross section area to total treatment area) are two key design parameters.. The typical stress concentration ratio for stone columns …
