The current world population ranges around 7 billion and is ever increasing; the rising population has created huge demand of land for various infrastructure facilities. This has pushed the engineering community to use land which previously in history was considered unsuitable for any construction. Soil liquefaction caused by earthquake loading is a major threat to infrastructure. Loose saturated sands when subjected to seismic loading develop high excess pore water pressures and shear strains that may lead to soil liquefaction. Deep vibratory compaction method is an established ground improvement technique for granular soils. This technique is used to improve the properties of loose to medium dense granular soils by compacting deep layers of the soil and therefore reducing settlements, increasing the vertical bearing capacity, and aiding in liquefaction mitigation. The lack of analytical design methodology and dependence on field experience of past projects to ascertain liquefaction mitigation potential inhibits the efficient use of deep vibratory compaction. This talk would highlight insights from a combination of physical modelling, field measurements and numerical simulations that were carried out to analyse deep vibratory compaction. Followed by seismic numerical simulations of saturated sand, compacted by deep vibratory compaction to analyse the feasibility and effectiveness of this method for mitigating the liquefaction hazard and its consequences.
