Relative contribution of drainage capacity of stone columns as a countermeasure against liquefaction

Physical modelling applied to infrastructure development

“…In particular, the use of drains (of various types) as mitigation against the effects of liquefaction is the subject of several papers. Paramasivam et al (2018), García-Torres et al 2018, Marques et al 2018and Kirkwood & Dashti (2018) all consider the use of vertical drains whilst Apostolou et al (2018) consider the use of stone columns although their tests did not represent structural loads but rather, investigated dissipation of excess pore water pressures within the soil model. Finally, although not strictly speaking a ground improvement technique, Nigorikawa et al (2018) describe a base isolation system as a mechanism to mitigate liquefaction effects.…”
