The results presented in this paper were obtained from a large testing program that was conducted to evaluate the post-liquefaction axial load capacities of three drilled shaft and three driven pile foundations constructed at the Turrell Arkansas testing site (TATS), located within the New Madrid Seismic Zone. An increase of side and toe resistances, significant ground and driven piles and drilled shafts top settlements were observed following blasting. This increase and settlements were attributed to the increase of effective stress as the excess porewater pressure dissipated. The liquefaction-induced dragloads that developed, at the neutral plane ranged from 200 to 650 kN. The load and settlement distribution curves for each installed foundation during the application of load to the top of each foundation and after blasting are also discussed. The induced dragloads represented more than 5 and 10% of the total resistance of the drilled shaft and driven pile foundations, respectively.
