摘要

Earthquake-induced liquefaction poses a formidable challenge to deep pile foundations owing to their susceptibility to substantial shear forces and bending moments during seismic events. This study explores the enhancement of pile performance after dynamically compacting liquefaction-prone soils. This method serves a dual purpose: it mitigates liquefaction and enhances the seismic resilience of the surrounding stratigraphy, both adjacent to and beneath the pile shaft. Consequently, it improves lateral load capacity and reduces the depth of pile fixity. Validation is conducted through rigorous comparison with Indian Standard code methodologies and Ensoft L-Pile software. This approach facilitates cost-effective design by effectively improving ground conditions, reducing pile vulnerability to future seismic loads, and conserving natural resources for future generations.
