Insights from the numerical analysis of axially loaded piles in liquefiable soils [PDF]
Axially loaded piles in liquefiable soils can undergo severe settlement due to an earthquake event. During shaking, the settlement is caused by the decreased shaft and tip capacity from excess pore pressures (ue) generated around the pile.

Performance-based assessment of liquefaction-induced downdrag on piles [PDF]
Earthquake-induced soil liquefaction can cause settlement around piles, which can translate to negative skin friction and the development of drag load and settlement of the piles. The overall phenomenon and the interaction of the individual mechanisms in

Full-Scale Testing of Blast-Induced Liquefaction Downdrag on Driven Piles in Sand [PDF]
, 2017 Deep foundations such as driven piles are often used to bypass liquefiable layers of soil and bear on more competent strata. When liquefaction occurs, the skin friction around the deep foundation goes to zero in the liquefiable layer.
