A Review on Ground Improvement with Surcharge in Addressing Liquefaction Mitigation
Soil liquefaction and associated ground deformations have been a major source of damage to structures in the event of earthquake. Various ground improvement techniques are being practiced in mitigating liquefaction, across the world. However, handling silty soils having fines content more than 20 percent attracts special attention to the practicing engineers when compare to clean loose sandy strata. Improvement of silty soils using vibro stone columns is proven technology as this process ensures overall increase in shear strength and soil stiffness (i.e., reduction in settlements). Furthermore, application of surcharge over the treated area will be an added advantage as the increase in effective stress ensures enhancing the consolidation process. This paper covers a case study of ground improvement with surcharge in consideration of design mythology. In addition, prediction of time rate of settlement, performance assessment is also discussed. Post treatment liquefaction analysis confirms the improvement in factor of safety against liquefaction.
