No. Name of Authors Model Type Numerical Procedure
1 [17] Guétif et al. 2007[18] Castro et al. 2010[19] Kirsch 2006 Axisymmetric model: 2D By imposing a uniform lateral displacement, which is equal to the final stone column average diameter.
2 [20] Foray et al. 2009 Volumetric model: 3D By using a uniform volumetric strain expansion of stone column.
3 [21] Elshazly et al. 2008[22] Elshazly et al. 2006 Back analysis from field test By varying the lateral to vertical stress ratio to obtain the field test behavior.

Stone Column Installation Method_

Method of Construction Construction Process Recommendation References
Displacement Method A closed-tip steel tube is pushed down into the soft soil and then the cylindrical frame of geotextile and fills is inserted into the empty hole. After that, the tip opens, and the tube is pulled upward under vibration. A very soft soil (for instance, cu < 15 kPa). [15] Alexiew et al. (2005)
Replacement Method An open steel pipe is installed into the soil until it reaches the hard layer, followed by the removal of the soil within the shaft via an auger boring. The potential for vibration to influence adjacent buildings. [16] Gniel et al. (2010)
