Liquefaction Mitigation In Silty Sands Using Stone Columns With Wick Drains, Michael James Quimby
Theses and Dissertations
Stone column treatment is commonly used to mitigate liquefaction hazard in sandy soils. Research and experience indicate that this method is effective for clean sands but that it may not be effective for silts and sands with fines contents greater than 15-20%.

Although this method is used in practice, there has not been a formal academic study of its effectiveness. This thesis evaluates seven different case histories where wick drains were used and one where wick …
